Spotted Ratings, Friday 5/4/12: Shark Attack

WHAT MATTERS:

• The big winner of the evening was ABC, as Shark Tank surged to finish 0.3 ahead of everyone else on the evening and tie its Friday high. Tank finished up a Big Bang Theory-esque 50% on its year-ago performance. They actually won every hour with Primetime: What Would You Do? and 20/20 also up.

• The Avengers effect was not all that significant, at least not for the shows you'd think. Fringe knocked down by just a tick and the other genre shows (NBC's Grimm and CW's Nikita and Supernatural) were unaffected.

• CBS got a little bit back in finals but still saw the whole lineup lose another tick from last week's already soft performances.
