An increasing number of people are watching video, including TV shows and movies, on their computers, instead of via traditional TV sets.
Many young people don’t even bother with a cable or satellite subscription and just use their PCs or Macs to get their video fix.
But computer screens are small, so some folks hook the computer up to the TV for their viewing sessions. The problem with this is that it can be complicated for the technically challenged. And it can involve long cables stretching across the floor, or leaving a computer you might want for other tasks permanently connected to the TV. So companies have been working on ways to beam Internet video wirelessly from your computer to your TV.
