TV shows that are popular with younger viewers are expected to get a ratings boost, thanks to a change in the way Nielsen Media Research does business.
In the past, 18-24-year-old viewers were counted only when they were living at home with their parents. Now, Nielsen will attempt to keep track of their viewing habits even when they're away at college. But critics say the system is still imperfect.
Robert Siegel talks with The New Yorker magazine's media critic, Ken Auletta, who says that networks like Comedy Central, with its edgy, satirical comedy that appeals to younger viewers, could see a jump in their ratings.
