I'm trying to decide if you are serious about this or "just playin'". On the chance that you are serious, consider a couple of things. Major media are all private, not government, enterprises. Apart from PBS, they receive no government funding. Consequently, if it made economic sense for someone to place a TV station in Bloomington, then someone would. While there is a lot of legitimate fodder served up from the Bloomington city government, this issue isn't in its purview.
Independent tv is largely dead in America, save for those originating from major US cities like NY, Chicago, Atl, where there have been historic connections. Nobody is going to start a TNT or WGN-style network in Bloomington, IN.
None of the major networks is going to license an affiliate in a market where they already have reach. Terre Haute serves a geographical area out of reach for over-the-air broadcasts anywhere else. Bloomington is within easy antenna reach of the network affiliates in both Indy and TH.
It's the same reason there are no longer small-town, single location, car dealerships or shoe repair businesses, or Sears Roebuck stores anchoring malls. The market won't support it.
WTIU does some IU programming and would likely do more if it had the financial wherewithal to do so. But things being what they are, it has to air what the national network provides it because that content is not costing WTIU money to produce or acquire.
