It's no surprise that newspapers and radio have lost audience share as online and digital news consumption increases. But television is also vulnerable, as a new Pew Research Center report  reveals. Fifty-five percent of people surveyed watched the news on television the day before, a sharp decline from 68 percent in the 1990s. Those who do get their news from TV are graying: Those 50 and up are more likely to watch TV news than they were in 2006, but only about one-third of 18- to 29-year-olds currently get news from TV, down from nearly one half six years ago. Exceptions are viewers of The Colbert Report  and The Daily Show , which have the youngest news audiences on TV.
