how come video dating never took off?

Remember in Singles, when Debbie Hunt does that video dating thing and ends up having to duke it out with her roommate for the Lance Armstrong biker dude? I wonder why that never caught on, but a few carefully retouched photos and some witty, oft pompous asides on a lame internet dating site have attracted millions. Think about it: on camera, talking, laughing, waving their arms, picking wax out of their ears, can show you a hell of a lot more about a person than knowing their favorite movie or Pokemon character. And God knows, with the latest glut of reality drivel, everyone wants to be on TV. Maybe there should be a cable channel dedicated to dating; it could be called "Channel Surf for Love" or something retarded like that. Or you could have a Blockbuster that only carries DVDs of people's single ads: you stroll in, pick up a couple of attractive DVD covers, read the back, and take one home. If you don't like 'em, return it and try someone else.
Ken, should I be patenting/copyrighting/suing for rights for this brilliant concept?
