Help with a MacBook cable

I've always been a PC guy, but my son needed a MacBook(?) for college (Journalism School) so that's what he got last year.

For Christmas, he said he would like a cable that can connect his MacBook to the HDMI connection on his TV. I have no idea what connection is on the Mac, can someone tell me what it is and I can Google it or search TigerDirect / NewEgg (or a link would be even better).

Thanks!

Thanks! Found it.
Looks like I'm needing a Mini-DVI to HDMI cable.
Apparently no one makes a single cable like that (didn't check the Apple store, but I'm sure it would be outragously priced like everything else from them). But I found a set: mini-DVI to DVI and DVI to HDMI.

Did find this for under $20!
