I think that the dude who owns ESPN owns TSN as well. On tsn.ca, it says that they (TSN) have been under new ownership since Sept. 2001. If I can remember correctly, this is the same time that TSN changed their sports news show's name to "SportsCentre", same as ESPN, and got that same theme music in the beginning. TSN has a sister station called ESPN Classic Canada, so that's where I get my theory from.
