|Depends on your TV. Some TVs have hardware mods that will allow you to add a Wireless NIC. These TVs are very expensive and hard to find. I doubt you have one. The only way to hook a standard to to the Internet is to hookup an old computer or laptop to it.|
I personally have a Desktop computer hooked to my TV that has a 7.1 surround sound audio card hooked into my stereo and a Blueray player and all the stuff I need for my home entertainment. I then purchased a Gyro Mouse (Like WII controller) and hooked the computer into my WiFi. This way I can access Hulu and Netflix from it. Its the way to go if you have the time and money but it really only cost around $1000.00 to put the system together.
If you want to go cheap then look into a WiFi Blueray player. Most have netflix but not Hulu yet. I personally like my computer because I can browse and play my MP3 songs on it that a blueray will not do.
