When I moved from Kansas to the Southeast, it was hard to keep watching the Chiefs play. They've not often been a bad team in my lifetime, but there were only sort of ok during the years from 2000-2010:

2000 7-9
2001 6-10
2002 8-8
2003 13-3 (Lost divisional playoffs)
2004 7-9
2005 10-6
2006 9-7 (Lost Wild Card Playoffs, Sunday Night & Thursday Night Football introduced!)
2007 4-12
2008 2-14
2009 4-12
2010 10-6 (Lost Wild Card Playoffs)

When I lived in Kansas, it was pretty certain if the Chiefs were playing, I could turn on the game and watch it. When I moved to Atlanta in 2000, I had to miss most of the games, which sucked. If the Chiefs played Sunday morning and the Atlanta Falcons were also playing on the same network, then Atlanta would be shown. Or Miami, or New Orleans, or Tennessee. You get the idea. Now if the Chiefs were on Monday Night Football, then I could watch - otherwise, probably not. If they made the playoffs, then I could watch, which happened 3 times in that decade, if you count 2010. The introduction of Thursday and Sunday night football helped and gave me a couple extra games a year. But mostly I was kept at a distance - highlights, score updates, post-game summaries. Not really as much fun to follow the team when you've already lost the excitement of 'what happens next'.

If I had been a bigger fan of football itself, I would have probably watched local teams, and maybe gotten into the Falcons or Titans or something. The other way teams achieve a lot of TV time is to be good. So maybe I would have gotten to watch a lot of Patriots/Steelers/Colts. Watching them would probably have lead to me rooting for them. Which is one way 'band-wagoning' happens, I think. Watch the team a lot, start rooting for the team you're watching.

Right now I still live in the southeast, but the Chiefs are good. So they're on TV almost every game. They still get pre-empted by Tennessee and Atlanta and a few other more regional teams, but they've made the playoffs every year for the past 10 years and done well most of those years. So the networks find ways to show them to me as much as possible. When they inevitably return to mediocrity or even fall to Sucksville, I'll have to make decisions about whether to stop watching again or pay for an all-games package or whatever. (It would be tough to pay a lot of money to watch a sucky Chiefs team lose - probably I would be content to watch... ugh... 'highlights'

If I lived in Kansas still and got almost every Chiefs game on standard network TV then none of that would matter and I would probably just continue watching them no matter how good/bad they become.
