The big assumption here is that the local news is covered by them. There is nothing local about the Tulsa World, not its ownership or the focus of its coverage, sports is just the easiest way to see that.
Thunder, OSU, OU pretty much any national story. Even their high school coverage slipped from the past. TU is an after thought of a oh yeah don't forget and ORU might as well not even exist.
Politics are similar, major news or breaking news is all about the state or a national issue. It really shouldn't surprise anyone, certainly not the national interests now controlling the World, that a local paper doesn't cover those stories as well or as thoroughly as bigger organizations who were always focused on that.
However it's much easier and more profitable to have five reporters writing the same stories for 60 newspapers than a full staff working for local tid bits and digging into things.
I get my news like most people, I see something of interest and then either use Google to get more in depth or if its truly local talk to the local people, we use to do that a lot too, but it happens less and less.
