How Do I Connect My Tv To The Internet?

I have a samsung flat screen. We don’t have cable or dish or directv. We LOVE to watch movies so I was considering getting netflix so we could get the movies instantly on our tv. Problem is I don’t know how to connect the tv to the internet. I should mention that the tv is right in front of the cable outlet (we have cable internet). All help appreciated. Also a cheap solution would be fantastic!

Building A Wall For A Flat Screen Tv. Where’s The Best Location For The Electrical Outlet?

When I hung my flatscreen I put the outlet directly behind the TV along with a cable outlet and ports for the surround sound and DVD player. When the TV is folded against the wall, It’s on a cantilever mount, you cant see the outlets wires or anything behind it at all.
