Why does ESPN not have an ESPN Bay Area?

That's a good question. Allegations of an East Coast bias - particularly a pro-New York bias - have been widely perceived in regards to ESPN for years, which may seen somewhat ironic given that its studios are located in Bristol, Connecticut outside of Hartford which has its own TV market separate from NYC. But there are underlying reasons why the Bay Area does not have its own ESPN Local site.

For starters, at this point, four of the five ESPN Local sites (Boston being the lone wolf) are located in markets where ESPN owns stations. It is assumed that ESPN is going to hold off on expanding beyond these areas until their Local experiment is proven. On a sidenote, the network owns five stations, with ESPN Radio 1250 in Pittsburgh being the only ESPN O&O without its own local site, and conventional wisdom and logic would have ESPN launching a local site in Philly before going to the Steelers' home turf. And as a further insult to injury, the San Francisco Bay Area does not even have an ESPN affiliate.

So if there is no ESPN Bay Area yet, these factors are are all but certain to be the reason. I should also mention that the Bay Area will eventually get its own ESPN Local site in the near future due to the size of the market. And you also forgot to mention soccer (Earthquakes) and the college scene (Stanford and Cal).

The Rays are in Florida. Florida is crammed with retired those who love baseball yet are literally not from Florida. Many are from north east states and stick with those communities(like the pink Sox). No followers, why tutor the video games.
