Let’s say, for example, that I’m tuning into ESPN SportsCenter for an update on the day’s sports action. If I’m just tuning in for some visual highlights, I don’t care who’s commentating, I’m just there to be entertained. If, however, I’m tuning in for scores and statistics of the day’s action, you know - facts, credibility at that point is integral to why I’m watching.
Brian Williams and NBC news have been exposed. If the viewers are merely tuning in to be amused by a few visual highlights of the day’s action, Williams and NBC remain in play. If, however, viewers want to be informed, they can decide for themselves if another news program provides a better product.
