Your History of Vidding

I'm running some vidding programming for the Fanfic track at Nine Worlds. In particular, I'm doing a talk on vidding, which I'm aiming at fans who probably read fic but don't necessarily know so much about vids.

Crowdsourcing a little bit of my research here - I'd really like to hear about other people's experiences of discovering vids.

I'd love to know about the first vids you can remember watching.

a) Which fandoms were they in?

b) Which websites did you hear about them from?
eta: that was poorly worded, lots of you saw your first vids offline via cons, tapeswaps etc. Tell me about that too!

I'm particularly interested in hearing about fandoms other than Western media fandoms, and websites other than LJ/DW, but all responses will be helpful!
