Ratings: So You Think You Can Dance down 17%, America's Got Talent wins

America's Got Talent had a 2.8 adult rating last night and 10.46 million viewers, enough to be the #1 show on Wednesday.

So You Think You Can Dance had a 2.0 rating down 17% from last week and 5.56 million viewers.

Looks like viewers switched as soon as AGT went on. SYTYCD skipping a week because of the Fourth of July Holiday also will not help.
