Why's it a firewire?

Went out to visit with mom today. Picked out some carpeting that I like for the basement, then went to Value Village and found some really cool photo collections of Vancouver, London and Expo 86! We had lunch and talked a lot about things, then went off to the mall. I went back to Future Shop to get a camcorder bag and a FireWire cable, which I needed to transfer video from the camcorder to my PC. There was only one cable to choose from, and it was $90!! Ouch. But it works and I had fun tonight transferring practice video and experimenting with various codecs.
