One in 10 people watch TV shows on something other than a TV set. And leading the way is the Apple iPad.
Many satellite and cable TV providers now offer apps taht allow subscribers to watch programs on an iPad.
Some limit users to video on demand, meaning watching after the programs have aired.
But there are apps from providers like Time Warner and Cablevision that allow live TV viewing.
The app from ESPN network also allows live viewing. Another advantage with ESPN's app is you can watch shows away from home. That's also true of some other network apps, but they only provide video on demand.
While most of the apps are free, at least to subscribers, consumers could be hit with other charges, Consumer Reports warned.
"If you're streaming on a wireless data plan, you could easily run up or even over your data limit," said Consumer Reports' Paul Reynolds.
If you have an iPhone or iPod Touch, there are some apps available to watch TV on those, too, and even a few for Android phones.
But be aware, if you get your television via satellite, there's an additional charge.
You'll have to pay for either a subscription to a high-definition DVR or buy a Slingbox adapter for $99.
