One possible solution to the abreviations that I have seen some TVs do is that at the start of the game and every once in a while they show an expanded score with the full names and than after a couple of seconds it goes back to the 3-letter names.

Writing the full team name all the time wastes some space and is sort of redundant. Not only are most people watching the game already aware of who the teams are (they wouldnt be watching otherwise) but the commentators are constantly saying the team names anyway.
