Case Discussion:
“Viacom Golden Years

The Question now is:
• Is Goldman right?
– Does one really “never know
y
g
anything?”
• Or, more correctly, can one
know better?
• Can one increase the probability
of being right?
• Viacom is considering to enter the retirementage market
– Through multiple platforms:

Why Demand Analysis?
Why Demand Analysis?
• Every industry & firm wants
to know
–Who its p
potential buyers
y are
–What their willingness to
pay is
–What their price sensitivity
38
is
- How to identify promotional
effectiveness
- How to identify market segments and
select target markets
• Etc
41
But it is Always Difficult To
Determine Demand
Why Demand Analysis?
–What product features they
value
–What
Wh t th
they lik
like about
b t
competing products
39
Why Demand Analysis?
- How to position its product
- How to plan the marketing and
promotion plan
- What
h the
h pricing
i i strategy should
h ld
be
- Deploy its sales force
- How to select and manage
40
distribution channels
• It’s easy to graph a hypothetical
demand curve in a theoretical
economics model
• But very hard in the real world to
determine actual nature of
demand, and the factors that go
42
into it
“Assume a
Demand Curve”
P
Q
But Where Exactly Is It?

Long Planning Horizons
Demand analysis is
particularly important
(and difficult) for media
and information firms
• Presence of non-maximizers
of profit who will supply
products
d t outside
t id the
th market
k t
• Continuous-flow products
(telecom services, cable TV,
newspapers, etc)
Why?
44
Recall the Fundamental Economic
Characteristics of Media
Long Planning Horizons
A. Supply Side

–Demand estimation is
essential to reduce risk of a
project

–Fiber-to-the-home
–Broadcast satellites
–Business plans
–IT equipment and semiconductors

Investment Uncertainty
• Outside investors must

• “Public Good” characteristics
• Media products often given
awayy rather then sold to
identifiable users. (e.g.,
broadcasting)
–Audiences must be identified
53
for advertisers
2. Instability of Preferences
4. Unstable Markets
1. Content suppliers must be
able to rapidly respond to
changing
g g audience tastes
• “Excess supply”
• “Accelerating Returns”
• “Price Deflation”
• “Convergent Supply
Industries”
–“Convergence of suppliers”
51
3. Unique Products
• For each discrete-product media,
Product is unique
-Films, books, music
-Therefore separate marketing
“drives” necessary for each of
thousands of new products
• Many products are “intangibles” and
hard to evaluate in advance
52

5. Technology Change
• For “new media”
and applications
–Rapid
p change
g
of technology
–Short product

Technology Change (Cont.)
• No consumer experience
with many new products
– e.g., MP3 players,
l
video cellphones, etc.
• Techno-optimism
(“push”)by producers
Iridium
56
6. The Subjective Value of
Information
• Information is an experienced good.
Its value is only determined after
consumption
consumption.
• Thus, research revealing the value
of information prior to consumption
is important to media providers.
S. Rafaell and D.R. Raben. “Experimental Investigation of the Subjective Value of Information in Trading,”
in the Journal of the Association for Information Systems, Vol. 4, 2003, pp.119-139.
57
7. Supply Affects Demand
• Media create a buzz for their own
product and references shapes
audience
58
8. “Network Effect”
• Media demand is interdependent with that
of others:
– Telecom, Internet: benefits to users rise
with numbers of others on the network
–For Film, TV, Music, popular
Magazines and Books: often share
experience with peers; a major benefit
of media consumption is to be
connected with one’s peers.
59
Implications
• Leads to “extremes” of
success because of the way
users dynamically
y
y influence
each other.
De Vany and Walls, “Motion Picture Profit, The Stable Paretian
Hypothesis, and the Curse of the Superstar,” forthcoming in the Journal of 60
Economic Dynamics and Control, 2004.
“Network Effect”
• The average utility of the
service increases with the
number of other
participants Therefore,
participants.
Therefore the
demand increases with size
of networks. The more
people are on the network,
or share the experience, the
more people are willing to
pay.

Media Flops
Type I and Type II errors
Book Flops are Bi-partisan
68
71
A Type I Error is the false rejection of a true null. It has a probability of alpha
(α). In other words, this error occurs as a result of the fact that we have to
somehow separate probable from improbable.

grossly over-estimated the DVD sales
for “Shrek 2.”
• Retailers returned millions of unsold
copies.

TV vs. Film
Type I and Type II errors
• Movie mogul Daryl Zanuck
“[Television] won’t be able to hold on to
any market it captures after the first six
months. People will soon get tired of
staring at a plywood box every night.

A Type II Error is the false retention of a false null. It has a probability equal to
beta (β).

True?
• Yes, True
• But task is not to be exactly
right, but to reduce the
probability of Type I and
Type II errors

• Social Science and
communications research have
not resolved this question.
• There is a continuous back-andforth between explanations
whether “powerful media” or
“powerful audiences” determine
media content.

• The meaning of media texts depends
on the cultural background of the
audience. (“Interpretive Communities”)

• For purposes of media
managment, both major
perspectives are correct
• Media audiences have preferences

How Do We Get From a
Sample to an Estimate of the
Overall Population Parameter?
•Suppose one takes 3 independent samples of the
same population.
•Question: Did you watch last week the “Golden
Golden
Age” Channel?
•But the samples may not be representative.

Case Discussion
• How many viewers tuned into
the “Golden Years Channel”
last week? The Nielsen panel
has 5000 households and
1250 of them say they
watched at least some of GYC
last month.
154
p = pˆ ± e
•Where
p̂ : audience share in sample
p: audience share in the population
e: margin of error
156
Sampling Error
•Sampling error (e)
–gives us some idea of the
pprecision of our statistical
estimate.
157
23
Potential Error in Estimate
• (e) = potential error,
due to sample being
“off”
• z-score: indicates how
far an item is deviated
from its distribution

Ordinary Least Squares (OLS)
• Use linear regression models
to quantify linear relationships
among variables
• Can estimate OLS regression
using statistical software
packages (STATA, SAS,
EXCEL, Minitab, etc.)
173
http://www.chass.utoronto.ca/~murdockj/eco310/F03_310_six.pdf
• Can use numerous variables
• Identify, track, and model key
variables (price, competition,
etc.) that affect demand, and
put them together in different
scenarios
171
Typical Regression Analysis
Unit sales = a + b1 price + b2 advertising +
bi other variables + e
or
Market share = a + b1 lagged market share
+ b2 price + bi other variables + e
Thomas T. Nagle & Reed K. Holden, “The Strategy and Tactics of Pricing: A Guide174
to
Profitable Decision Making,” Second Edition 1995
Other Control Variables
• Adding variables that might
affect sales, such as
–Growth in GNP
–Growth in population
–Season
–Income level
172

• Demographic characteristics
include age, education, gender,
marital status
• Psychographic characteristics are
concerned with the individual’s
lifestyle preferences- their
activities, interests and opinions,
which marketers refer to as
consumer AIOs.

Approaches to Forecast
Newsprint Demand
1. The classical model: (FAO model)
(UN’s Food & Agriculture
Organization)
g
) estimated demand for
newsprint as based on income levels
(GDP)
• Since GDP is rising, demand is also
rising
Lauri Hetemäki & Michael Obersteiner, “US Newsprint Demand Forecasts to 2020,”
184
supported by Fisher Center for the Strategic Use of Information Technology.
Trends
• But in fact the newsprint
demand turned negative after
1987, despite rising GDP.
• So FAO model
did not predict
well

A Second Model: the
“Regional Plan Association
(RPA) Model”
186
• “Print media price index” –
calculates the impact of changes
in print industry input prices,
which affects the printing and
publishing industries, and in
turn newsprint demand

3rd Model:
ln(d news ,t ) = γ 0 + γ 1Δ ln(circnews ,t ) + γ 2 ln(d news ,t −1 ) + μt
191
• A 1% increase in newspaper
circulation would lead to a very
large increase (3
(3.1%)
1%) in demand
for newsprint

The Demand Model
Price Sensitivity
• In a situation of two competing
home video game firms, the
demand model for each firm is:
• Sega’s price sensitivity is
relatively smaller than Nintendo’s,
because customers are more
willing to pay more for a product
technology supported by a large
network of users.

• Similarly, Sega’s advertising is
also more effective compared to
that of Nintendo

Problems of Econometric
Demand Estimation
• Data
–Often insufficient
–Often unreliable
234
• Need to assume a specific
mathematical model for the
relationship between price and sale.
• If specification is incorrect, the
results will be incorrect
• Predicting the future requires
assumption that behavior is like the
past.

• A simple demand model could
be specified like this:
Likelihood of watching the Golden

education
δ= cross elasticity to other types of
channels
g
e = “network effect”
f = effect of other factors z
u = error term
242
Y = time of day
Measuring the Price
Elasticity of Demand:
this is discussed in
detail in the Chapter on

M d l
Models
270
Generally, adoption of a new
product follows an S-Curve
Pattern
268
271
42
S-Curve Pattern of Adoption
• The S-Curve helps to illustrate and
to predict how a new product will
be accepted by the population
• The S-shaped curve of adoption
rises slowly at first when there are
few adopters
• Also known as an “epidemic
model.” A “logistic” function
y(t)
(t) = N{1+0 exp [-kt]}
[ kt]}
272
General Formula of the SCurve
a
Cumulative sales =
1 + be− kt
where t is time and a, b and k
are constants.
275
• Example: Adoption of
Blue-Ray DVD
• Example: knowledge of a
hit movie

Viral Marketing operates on an
S-Curve
• Knowledge of the given thing will
spread like a “virus” epidemic

Market Growth Curves
Example #1: DVD vs. VHS
• Can the diffusion of DVD
be compared to the
diffusion of VHS?
278
Problems
281
• VHS is in 95% of US HHs in
2008 (= Maximum Market
Demand);
–DVD penetration was 75%, in
2008.
• finding acceleration point
• finding

282
• comparison of the product to
be forecast with some earlier
pproduct that is believed to
have been similar
280
283
44
75 x 100
= 79%
–Thus, the HDI =
95
– Thus, the DVD market is
still 21% below its potential.
• Problems with the diffusion
approach: There are too
many differentiating
diff
ti ti variables
i bl
to make comparisons among
products have a strong
predictive value.
284
287
• VCR reached 75% after 12
years. DVD took only 6 years.
Hence DVD penetration rate is
2x faster than that of VCR.
• Since VCR took 3 years to rise
from 75% to 95%
- hence, DVD is likely to take
only 4/2 =2 years to reach 90%285
• For Blu-ray DVD, can one
make similar comparisons to
DVD
• But, maybe consumers do not
value HD much over SD
quality?

when you know that you
ultimately control the final cut
on your movies. Buy it’s
frightening if you’re in a

take the results of that
preview re-cut the film based
on that, maybe consulting you
or maybe not. That’s

Early TV audiences: Diary
System
• Traditional Nielsen
methodology, especially for
local TV markets.
- used 4x a year during
“sweeps” periods for local
stations.
• viewers record TV viewing 420
1. Diary System
• opportunity for samples to lie
• misses responses from
children,, travelers,, and
TV viewing in bars
• difficult with channel surfing
421
67
Sample Bias
• In the past, response rates of 70%
for diaries.
• Today it is difficult to get 50%
response rate for a meter panel,
25% ffor a di
diary
• If the people who do not respond
view TV differently from those
that do, then the ratings are biased
and wrong.

People Meters: Pro
• Older people have higher
refusal rate to participate
• Young men most willing

• instant measures

• no “lying”
429
432
Also, the greater audience
fragmentation creates greater
relative unreliability of results
People Meters: Con
• children, travelers, and bar
viewing not captured
• nobody may be watching
• requires viewers to identify
themselves
• The % of standard deviation
tends to grow as ratings
become smaller.

• E.g.: a “true” ratings of 6, in
sample of 3,000, will show as
sample ratings between 5.2 and
6.8 (± .8) in 95% of samples.
–i.e. relative error is ±14%
• But same error for “true” rating
of only 2 (± .5) will have a
relative error of ±25%
434
• And for a small cable channel
with “true” rating of .3, ±.2, the
relative error is ±65%

• In theory GYC could benefit from the fast and

Example for CUME:
Radio Station #1
• If an advertiser uses four
different programs with
respective ratings of 15, 22,
19, andd 27, the
h weekly
kl GRP
becomes the sum, or 83 GRP

4. The Audience Metric #5 or
CUME
• Reach (or CUME)
http://www.all-businesslogo.com/images/update/29aug
2004/Z100__38930.gif
• measures # of viewers or
listeners per week of a channel
• viewers counted once per week
• Useful for cable channels or
519
radio stations
521
CUME: Radio Station #1
Interpretation: station attracts
large numbers of people in a
week but does not keep them
–few listeners at any given time
• Station promotes itself well, but
does not have good
programming to keep listeners
522
Example for CUME/AQH
Radio Station #2
Audience Metric #6
Average Quarter Home
Audience (AQH)
• Station with CUME 10,000
(low) and AQH of 2,500 (high)
• Average audiences for major
time periods of the day
• Shows how many people are
reached over a week
520
523
84
CUME: Station #2
–InSmall but loyal audience
–25% of overall listeners
are listening
g at anyy
moment
• creases the chance that ads
will be heard by continually
tuned-in audience
Average Frequency (AF)
• AF=AQH x Number of
Spots Per Week/CUME
• Number of Spots per Week=
{(AF x CUME)/AQH}
524
Audience Metric #7: Average
Frequency (AF) of Exposure
• Used to calculate how many
times an ad must be p
played
y so
the average listener will hear
it, for example, 3 times
527
Example for AF: Radio
Station #1
• Assume (AQH=150, CUME=20,000
• To obtain Average Frequency of 3:
{(3 x 20,000)/150}
={(60,000/150)}=400
Result: Needs 400 ad spots per week
to reach average listener 3x

Audience Measurement:
“Quads”
Media Metric
#9: Quads
554
Nielsen-Type Ratings Measure
Only The Number of Viewer
• It’s a quantity, not the quality
of viewing
• Does not determine the
intensity of preference of
audience.
555
• To measure qualitatively, not
just quantitatively, requires
“attitude measurement”
techniques:
–focus
f
groups
–in-depth interviews
• Tool used by TV networks to
study viewing behavior
• 2 factors taken into account:
–tuning length/episode
(program’s “holding power”)
–frequency of viewing
(“loyalty”) to program
557
Quads distinguish 4 viewer
types
• “Gold cards”:
–watch over 75% of an episode
–Watch
Watch over 55% of episodes
shown in analysis period
• “Occasionally committed:”
–watch 75% of program, < 50%

• Respondents also indicate
which stars are their “favorites”
567
• High performer Q and high

pp raises a show’s
overall appeal.
• A high Q score for a show often
means that viewers watch more

• This means the Q rating can
be high if a performer is
extremely well-liked by a
core group

• The cost of laboratory
experiment is much smaller
than for in-store testing.
• Popular approach by
consumer electronics makers
• “Dry Test”
- the product is tested without

- solicitation letters sent out to
potential readers
- the first issue may be years away

Site-Level Measurement
• Basically, a self reporting
system by the website or visitor,
• Can potential identify users /
user types/countries, etc.
• Tabulations of page requests
• Most commonly used by
websites

• Browser-based measurement tool
• Makes variety of data available to
media owners
Uses for Internet Ratings
• Total website hits can be used
as the basis for determining
unique

How to Individualize
Information about a Web-site’s
Audience
Server Level Collection
• “Packet sniffing”
–Monitors network traffic
coming to a website and
directly extracts usage data
from TCP/IP packets.

Site-Level’s Systematic
Measurement Biases
• Registration requirements do
not workk well
ll
– Effort to users
– Privacy concern
– fear of spam
713
Major Tool: Cookies
• Overcounting
– repeat visitors
– counts not just people but also bots
and spiders
• Undercounts cached pages
• Can’t distinguish multiple users on of
same computer
711
• Cookies combine the control advantages of a
site-centric approach with the
individualization of the user-centric approach
• A standard programming device that
produces electronic files to tag individual
customers with a unique identification.
– Allows a website to recognize an
individual.

Click-Through (CTR)
Software
• Measures whether user clicked
on an ad to link to the advertiser
• Major Abuses of Pay-PerClick:
–“Click fraud” not illegal
–Portals like Yahoo have
disincentive to crack down,,
incentive to click fraud, through
sharing of PPC that are charges to
advertisers
–Attempts for techno-fixes have
failed
717
720
• Valuable to advertisers:
measures actual effect of web
advertisement; unique to
Internet
• Some per-click payments quite
high--$20!
• Usually < 1$

Advantages of User-Level
Approach
• Uniform measurement -->
comparability

• Counts pages actually received
• Measures actual behavior (not
self-reported)
• No conflict of interest

Data Mining
• Total time spent on a Web page
and total time spent scrolling the
mouse is a reliable indicator of
interest.
• The number of mouse clicks is
not a good indicator of interest

“GYC: Historical
Analogy
• “Golden Years” can forecast
GYC’s market penetration by
analyzing the growth of a
similar channel.
764
• And if there is no channel
dedicated to people 65+, it may
be possible to make estimations
based on the growth of a channel
targeted for a specific population,
such “Lifetime” television for

products
• Characteristics of viewers/readers
• Willingness to pay
• Characteristics of non-buyers
• Interest by advertisers
• How to portion its products
• How to plan marketing strategy
• How to plan pricing strategy
• What the audience likes/dislikes about
767
• We now understand better the
potential actions and their
effectiveness.
768
To predict the audience for the
GY cable channel
• We asked the questions
- how can Viacom determine
demand and related
information for still non
nonexistent products
• Early planning: - personal surveys
- Focus groups
- Conjoint analysis
- Delphi Surveys
- Diffusion studies

For Golden Years Magazine
• Same as for GY Channel, thus
achieving synergies
- add: direct mail test grid survey
- add: actual rates data
- add: surveys of actual subscribers
- drop: people meters and cable box

- Focus groups
- Test marketing
- Psycho-physiological tests

Thus, strength in data collection
But how is the data used?
This is the weakness: research follow on
Current methodologies are pretty impractical
- econometrics (need data, must project past
into future)
- identification of references by sociodemographics
- epidemic model projections
- trade-off (conjoint)
Should media companies
use demand estimation
techniques, like a car
manufacturer or an
airline?

So we covered a lot of ground.
But a last and important
question remains beyond
techniques, and technologies,
and technocratic
management: whether such
techniques are really what
media firms need

“There’s always been a balance
between educating your reader
and serving
gy
your reader… you
y
obviously balance telling them
what you think they ought to
read with giving them what they
want to read…”
• As often the case, both side are
partly right.
• Advertising, PR, and media
content itself shape
p public
p
• But audiences also reward
originality, and many do not
want to be pandered.
788
Recall the earlier question:
• Does the audience’s demand
shape the content supply?
• Or does supply—by large
media firms—shape viewer
preferences and demand?
791
• Creativity required not only in
the media product itself,
•But also in understanding the
audience’s needs,, tastes,,
preferences, desires, fears.
789
•These demand factors are often
subconscious, unarticulated by
792
audience
So, is demand analysis
• Are media demand-driven?
–As much of the audience
research techniques imply?
• Or are they supply-driven? As
marketing activities imply?
790
• “bean-counting” by uncreative
minds
• Tool for pandering to audiences
rather than of leadingg them?

environment, with
fragmented audiences, and
much greater choice, and
shorter attention spans
• These tools provide

Demand Analysis Becomes
More Important
• The greater the uncertainty
• The greater the upfront
investment
• The greater the economies of
scale and network effects
• The more competitive alternatives
806
• The shorter the product cycle
• Reliance on the “gut feeling”
“intuition” of “single-minded
entrepreneurs and of internal
advocates can be the most
expensive way to learn.
And therefore, I
disagree with the
slogan that “Nobody
Nobody
Knows Anything”.
809
One can improve the odds
• Slightly, but that is enough
for a competitive advantage
807
• Suppose a film has
Cost = $50 mil.
(Probability) P = 20% to gross $250 mil.
(Expected Return) E (R) = .2 x 250 = $50 mil.
E (Profit) = $50 mil cost- $50 mil [E (R)]= 0
• If one can improve the odds from 20% to
22% by
b smarter ddemand
d analysis.
l i
E (Profit) = .22 x 250 = $55 mil
ΔE (Profit) = $5 mil
• Now profit expectation is positive
