Nearly two-fifths (38%) of all U.S. households have at least one television set connected to the Internet, up from 30% last year and 24% two years ago, according to a new study from Leichtman Research Group.

The TVs could be sets with their own connection or could be connected via a videogame system, Blu-ray Disc player, Apple TV or Roku set-top box. These findings are based on a survey of 1,251 households nationwide that was primarily conducted in February 2012 and are part of a new LRG study, "Emerging Video Services VI."

In another sign of the growing importance of game consoles in delivering video into the homes, videogame systems were the primary connection, with 28% of all households owning a video game system connected to the Internet. Just 4% of all households are connected solely via an Internet-enabled TV set, and Apple TV or Roku set-tops are the only connected devices in 1% of all households.

While the study found growing penetration of connected devices, it did not find that this shift in viewing patterns was reducing multichannel subscriptions.

Overall, 1.6% of households were not subscribing to a multichannel-video service but had previously subscribed to one in the past year. In addition, just 0.1% of the respondents who dropped service in the past year and do not plan to subscribe again in the next six months told researchers that they don't subscribe to pay-TV because of Netflix or because they can watch all that they want on the Internet or in other ways.
