Fast National ratings for June 17, 2014.

Even without competition from the NBA Finals, NBC's "America's Got Talent" and "Night Shift" were both down week to week, but even in decline the two shows swept their hours and led NBC to Tuesday domination in all measures.

After benching "Riot" and "I Wanna Marry 'Harry,'" FOX got only marginal improvement from a quartet of comedy repeats, while the already tepid interest in The CW's "Famous in 12" may be dwindling.
