If you connect them they will come. The number of Americans who regularly watch movies and TV shows online has doubled in the past year, to more than 20 million, a new study by Parks Associates shows. According to the researchers, the growth is highly correlated with the increase over that time in the number of set-top boxes, Blu-ray players and HDTV sets with broadband connectivity. At the same time U.S. households are spending an average of $115 per month on subscription content services, according to NPD Group, up 8 percent from last year. So does that mean consumers will pay for content online after all? Depends on how it’s packaged. Bundle it in with something they’re already paying for and they just might. So remind me, why aren’t cable operators planning to charge for TV Everywhere?
