Electric current is still run over the cable. Ike is right in that quality matters little in cables that are 6-8 feet but once you start going up to 12 feet, the lesser quality cables tend to choke up and the recieving component can't tell if it's receiving 1s or 0s and you get picture degredation.
If you need anything longer then 6 feet might wanna spend the money on a quality cable.

"Here we see the degradation of the HD signal after 15 ft and 30 feet of HDMI cable. After 15 ft, the HDMI EYE pattern degrades and closes. After ~30 feet, the EYE pattern closes completely. A diminished EYE opening introduces bit errors in the HDMI receiver which leads to "snow" in the HD picture. In the case of the 30 ft cable, the video signal will be un-recoverable at the HD display."
