I grew up a fan of all sports Philadelphia. My only non-Philly team was the Orioles (b/c I grew up in Maryland).
I started following the Rays not too long ago b/c I got tired of not being able to watch my team on TV. I also started going to games...that's when I really made the switch. It's been hard for me to give up on the Eagles, Phillies, and Flyers though. They seem to get a lot more national coverage. I'm really trying to switch over to local teams, but it's so hard to pull for a different team after so long.
