After 28 weeks of the 2008-9 season, through April 5, 2009, ABC and NBC continue to be nearly tied in the main age demos we track. Of course, if you consider that about 10% of NBC's averages are due to the Super Bowl week alone, ABC would otherwise be well ahead of NBC across the board.
Fox didn't cut into CBS' season lead at all in adults 25-54 during the past week. I thought it would be likely that Fox would pass CBS before the end of the season, but that prediction looks to be in some doubt now.
