Lost on the Web: Does Web Distribution Stimulate or Depress Television Viewing? Joel Waldfogel The Wharton School University of Pennsylvania
Introduction • YouTube: • Site hosting video • User-generated • Network content • Appeared in Feb 2005, rapid growth • Top 10 sites within year • Time’s Innovation of the Year ’06 • My question: effect on television viewing (on network controlled viewing)
YouTube Growth We’ve been living through an “experiment”
Enter the Lawyers March ’07: Viacom demands $1,000,000,000
Networks post shows online • late ‘05 and early ‘06 • ABC, NBC sell episodes on iTunes • CBS at Google Video Store • Experiments in free distribution • May ’06 – ABC free on web • Fall ’06 – all major networks offering multiple shows online free • Today: lots of shows available free
…which brings us to the question: • How do unauthorized and authorized web distribution of network content affect television viewing? • Study a relevantconvenience sampleduring a period of change • Relevant: intense web users • Convenient: on campus • …during growth of web distribution
Cf. file sharing literature • Music • Close substitute, quick and easy to get • Divided attention • Most studies: some displacement, not 1:1 • Movies • Web offers poor substitute, DVD copying better • Undivided attention • Nearly 1:1 displacement • TV different? • Episodes complements • Demand stimulation plausible
Theory: life without YouTube • Watch conventional television when valuation exceeds “price” • “price” is willingness to watch commercials, adapt lifestyle to program schedule • (Similar to TiVo)
Life with web distribution • Holding distribution of valuations constant, effects depends on whether v > p0. • If “low valuation” viewers watch online, then DWL↓, no reduction in TV viewing. • But: free episodes online can shift out distribution of valuations. • Even more than in music or movies, ambiguous effects
Data: Survey of ≈300 Penn students • How often do you watch video material obtained over the web? What authorized and unauthorized sites/sources do you use (e.g. YouTube, BitTorrent, abc.com)? • Since Fall 2006, how many hours per week do you spend viewing • Authorized video on the web? • Unauthorized video on the web • Traditional television • list TV shows you watched during the 2006-2007 television season • Authorized web, unauthorized web, TV; frequently or sometimes. • Ditto for 2005-2006 season
Sites used • Unauthorized • YouTube dominant • tv-links.co.uk, peekvid.com, and bittorrent • Authorized • abc.com, nbc.com, fox.com, cbs.com, and cnn.com
Shows watched • TV: Grey’s Anatomy, Entourage, and The Daily Show • Authorized Web: Anatomy, Lost, and The Daily Show • Unauthorized web: The Daily Show, South Park, and Scrubs
Series Viewing Growth: ’05-’07 • Web viewing up • Unauthorized doubles • Authorized triples – big network response worked • TV flat
Empirical Approaches • CX: do people watching more series on the web watch fewer on TV • Longitudinal • Aggregate: do people whose web viewing rises between seasons experience bigger changes in TV series viewing?
Basic CX Approach • TV= number of series watched on conventional television, • WF = number of series watched frequently on the web • WS = number of series watched sometimes on the web • X = characteristics of the respondent (age, gender, etc.), and • ε = unobserved determinant’s of the respondents’ television viewing. • “do people who watch more series on the web watch more or fewer series on conventional TV?”
Disaggregated CX approach • Break variables into auth & unauth components: • WF = UNF + AUF, etc • Concern: unobservables correlated with WF, WS • (people who like TV like it via all media)
Cross section evidence -05/06 No differences between auth & unaith channels Those who watch more shows frequently on the web watch fewer shows on TV This operates through shows viewed freq’ly on TV
Cross section evidence -06/07 Unauth’d coefs more negative Similar, but positive coefficients in sometimes regression
CX interpretation • Lots of positive coefficients • Consistent with unobserved het or complementarity • What’s interesting? • Some actual negative coefficients, suggesting substitution
Longitudinal approach • Attempt to get around unobserved heterogeneity • difference across seasons
Figure 3: Change in Frequent Viewing on Web (Unauthorized) and Television Rho = -0.20
Figure 4: Change in Frequent Viewing on Web (Authorized) and Television rho = -0.20 here too
Estimating equation • Analogous to CX specification
Longitudinal estimates Small effects overall Positive coefs on sometimes Little sig diff auth vs unath Negative effects on freq’ly, esp freq on freq
Longitudinal bottom line • Smaller than CX magnitudes • Evaluating at 2006-07 web viewing: • TVF downby 0.36 • TVS up by 0.55
Translating series viewing into hours • How do numbers of series viewed “frequently” or “sometimes” on TV map into weekly hours?
Results on hours of viewing • Implied change in weekly hours • Authorized web = 1.78 • Unauthorized web = 2.26 • Overall, TV down 0.24 hours, web viewing up 4.04 hours • Effect on networks depends on value of viewers on TV vs authorized web
Conclusion • Substantial use of web in this sample • Half of TV viewing • From zero, large growth in web viewing… • …with small reduction in TV viewing • Less displacement than in movies and music • Movies (1:1) … music (less) …TV ( none?) • Caveats: • Convenience sample • Would be nice to study broader population
