　★★　Live TV Is For Old People: Time Shifting And Online Make Up Nearly Half Of All Viewing

　　http://techcrunch.com/2010/08/30/video-time-shifting-online-half/

Between online video, DVRs, and on-demand cable the amount of time people spend watching live TV (you know, with all of those commercials that advertisers spend $70 billion a year on) is shrinking fast. Only 52 percent of American’s viewing time is spent on live TV compared to online and time-shifting alternatives, according to a new survey of 1,000 American consumers by market research firm Morpace. And that percentage decreases the younger the audience, with the key 18-to-34-year-old demographic watching live TV only 41 percent of the time, versus 64 percent of the time for those 55 and older.

one of the major reasons viewing habits are changing is because people are watching video on a lot of different devices. While 96 percent of respondents watch TVs, 59 percent use at least one other media-viewing device. These include laptops (40 percent), desktop computers (36 percent), mobile phones (9 percent), dedicated media players (8 percent), netbooks (4 percent), and tablet computers (2 percent).
