If you have an Internet-infused TV set, apparently the apps you've just got to have are Netflix and YouTube.
The streaming video apps top the list of most popular smart-TV apps for current owners and consumers, according to a recent Harris Interactive poll.
Facebook, Amazon Instant Video and Pandora round out the poll's top five.
That's probably encouraging for manufacturers, eager to translate the popularity of apps on mobile devices into sales of the larger, more sedentary screens they sell.
"It is only a matter of time before we see the mainstream use of additional content apps, such as Facebook, being used on the TV," Manny Flores, senior vice president at Harris Interactive, said in the news release.
