If you want a "for example" of a home town newspaper becoming a homer newspaper, look no further than the Austin American-Statesman. They've always had heavy UTx coverage. Not surprising as I would guess 2/3 of their readers are and have always been Longhorn fans of some degree of rabidness.
As their newspaper has hollowed, the "everybody else" is gone while the heavy Longhorn coverage has not. For example, last weekend the American-Statesman had no one mention of the TCU@TTech game. Not even a box score. There may not have been any B12 games in which the Longhorns were not a participant that drew a mention. They had brief articles about the Aggies, and the Texas State Bobcats. Passing glances at games involving top-10 teams. Otherwise, all-UTx, all the time.
At least their sportswriters aren't cheerleaders, at least when the Longhorns are losing. HehHeh.
