SAN FRANCISCO: A media revolution is taking place, and most people over 35 years of age aren’t tuned in. Millennials and their successors are shunning old-school television in favor of watching what they want whenever they wish on Google-owned YouTube or other video platforms like Dailymotion or Facebook. “Young people don’t really watch TV any more; they watch online videos that are shorter and more talent-driven,” says Fabienne Fourquet, a former executive at A&E Television and France’s Canal+ who now heads the multichannel network 2btube. “They don’t want to be Hollywood stars when they grow up, they want to be YouTubers. There is this whole other world.” The new multichannel networks, or MCNs, are talent agents of sorts for creators of videos shared at online venues.
