Clash of the Titans: Does Internet use Reduce Television Viewing?
研究了互联网使用对美国电视观看时间的影响，发现对年轻人有适度减少作用，但对老年人无影响，且整体效应可能随时间增强。
We examine the impact of the Internet on the leading American recreation activity: watching television. We run a panel regression using television viewing, Internet penetration, and socioeconomic variables for a large number of American cities starting before the birth of the Web. We find that the Internet's effect on television viewing varies by age group, reducing it by a moderate amount for the youngest Americans but having no impact on the viewing of the oldest Americans. We hypothesize that the overall effect is likely to increase over time as older age groups have more experience with the Internet's recreational opportunities. © 2011 The President and Fellows of Harvard College and the Massachusetts Institute of Technology.
