Does your dad have a man cave where he likes to relax and watch television? Does he talk a lot about the "good old days of television" before reality TV? Is he a fan of obscure films and documentaries? If you've answered yes to any of these questions, hooking dad's television up to the Internet might be the ideal gift.
There are many ways to achieve Internet connectivity. You could build or buy a media PC and connect it directly to your dad's television. There are several products on the market that are relatively user friendly. But if this seems a bit too complex for your dad, there are other options.
Set-top boxes like the Roku, Boxee and Apple TV can give dad access to content from the Internet on his biggest screen. Video game consoles like the Wii, Xbox 360 and PS3 also include options to access content from providers like Netflix or Hulu.
If dad travels around a lot, he might appreciate a Slingbox. These devices connect to your television and then stream out the content over your home's network. You can access the content on a computer, tablet or smartphone -- even if you're hundreds of miles away.
