"I used to think my life was so empty. Used to think life was passing me by. I was just about ready, to curl up and die. Then one day I got a visit, from the cable company. They hooked me up, plugged me right in; now I've got cable TV." - Weird Al Yankovic.
Traditionally, cable television signals were delivered using coaxial cables (copper wire). More recently cable has been delivered by fiber optic cables (e.g. FiOS), and by satellite wirelessly.
