According to the ratings. From ACC Now:
The network has announced the game pulled in an average overnight household rating/share of 3.4/7, up 183 percent from the comparable window in 2008, which earned a 1.2/2 for coverage of Purdue vs. Michigan, in the metered markets.
Sunday’s result was the highest rating (nationally) for a regular-season NCAA basketball game on CBS since a 3.9/8 for No. 6-ranked Duke vs. No. 2-ranked North Carolina on March 6, 2005.
The Raleigh-Durham area pulled a 20.2 which is not shocking neither is the fact UNC-Duke blows away your run of the mill Big Ten game or that you have to go back to a previous UNC-Duke game to find comparable ratings.
