Douglas Pucci (@SonoftheBronx Twitter) has tweeted ratings for GSN from the week of May 25-31. The primetime (8-11pm ET all seven days) and total day (8am-4am ET all seven days) have been released, which are 460K/322K.
This is a ten-week high for the primetime average. The primetime average has not been this high since the week of March 16-22 (when it was at 459K viewers). The total day average hit a nine-week high last week, which has not been this high since March 23-29 (when it was at 326K viewers).
A lot of the high ratings can be placed on Idiotest from Wednesday and Family Feud from Sunday of last week. Idiotest averaged 455,000 total viewers in the 8pm hour on Wednesday. Family Feud averaged 732,000 total viewers over the three hours in primetime on Sunday. Week to week, Idiotest and Family Feud are at the top of ratings for GSN while The Chase reruns perform well but much better in new runs (which return July 16th).
