About 760! It's been going since 1963

The new series / reboot / revival started in 2005; the current season is the fifth since then. There have been three doctors since 2005: Christopher Eccleston, David Tennant and the current Doctor, Matt Smith. I think the current season is written so you can pick it up quite easily as a newcomer, but if you enjoy it, you might want to start with Eccleston's season and catch up.
Try some of the "classic" 60s and 70s series too: Tom Baker gives the iconic performance.
