Daytime is Facebook time, not TV time, for most media consumers. Facebook is closing in on being a mass medium -- just like TV, according to a study by Frank N. Magid Associates Generational Strategies. More consumers use Facebook during workday hours -- 9 p.m. to 5 p.m. --than watch TV. The survey says only baby boomers are the exception -- 35% report they are watching TV, versus 26% who say they are using Facebook. Thirty-two percent of Gen Xers -- those 35-46 -- use Facebook during daytime. compared to 28% who watch television. Those 18-34 are using Facebook 44% compared to 32% for television. Teen millennials use Facebook 30% versus 24% for TV. Younger groups 8-14, which the study calls "iGens," are the only younger viewers to give TV parity compared to Facebook -- at 16% each. Things are different in prime time, where TV still dominates. Looking at 18-34 viewers/consumers, for example, 49% are using Facebook versus 24% who watch TV between 8 p.m. and 11 p.m. Even those hours after-work and before prime hours give the advantage to TV for these younger viewers/consumers: 43% versus 39%. Baby boomers 47 to 65 are the biggest users of TV in prime time, with a 70% number. Those 8-14 are using TV at 39%. During prime time, the greatest usage for Facebook comes from teens 15-17, at 39%. The lowest usage is among the older crowd, 47 to 65 years, at 21%.
