Nielsen finds a pretty giant glitch in its ratings

The good people at Nielsen, the television ratings company, said today they’ve discovered a glitch. Bloomberg reports some of their ratings have been wrong for oh…the past six months or so.

People were counted as watching one network when, in fact, they were watching a different one. Looks like ABC was the big winner.

Nielsen ratings are, of course, worth bazoodles of dollars because that’s what advertising rates are based on.
