Many Americans – probably including you -- don't watch TV the way your grandparents did. Except for live sports, there's not much reason to tune in at a scheduled time. Your generation and young adults often watch videos from Netflix or Hulu Plus. Those digital streaming options without ads are expanding.

CBS, the only big broadcast network not on Hulu, just started streaming videos on a service called CBS All Access. HBO will start selling a version of its service online in 2015, the company said last week. Dish, Sony, and Verizon plan similar moves by the middle of next year. Disney also shows interest in direct-to-viewer programming that bypasses a cable or satellite dish service. They all want to reach "young consumers in the place and manner in which they watch," New York Times media columnist David Carr wrote last week.

An online survey of 1,159 people two months ago shows that 24 percent of those aged 18 to 34 don’t subscribe to a traditional pay-TV distributor. Sixty-one percent pay for streaming video. The number of Americans who buy TV programming through cable, satellite or fiber services fell by more than a quarter of a million in 2013, the first full-year decline, according to another research firm.

Journalists say: "CBS, HBO and other media giants are placing multiple bets on the future of TV -- so that they're protected no matter what happens." – Brian Stelter and Frank Pallotta at CNN.com

Magazine writer says: "Younger Americans . . . find the mess of streaming options "easier to deal with than a cable box and a Comcast representative." – Derek Thompson in The Atlantic
