With the recent success of Steve Harvey's Family Feud garnering a 6.3 household rating (9.3 million viewers) the week of January 27-31, GSN will have a harder time acquiring more episodes of Family Feud. This 6.3 household rating (which in female and 25-54 demographics beats Jeopardy! and Wheel of Fortune) is the highest since Family Feud premiered in 1976.
GSN first acquired the first two seasons of Steve Harvey's Family Feud (2010-11 and 2011-12) in March 2012, when the series just topped a 3.0 rating regularly, which was double of John O'Hurley's version in syndication, which was hovering around a 1.5 during the 2009-10 season and near cancellation. Now, Steve Harvey's Family Feud has averaged 5.0's and low 6.0's throughout the 2013-14 season thanks to double-run late-day timeslots in most affiliates.
Bottom line: When most shows go up in the ratings, they get harder and more expensive to acquire.
I'm not sure at all when the 2012-13 season of Family Feud will come along. My guess would be April, with an announcement in March. This is the first HD broadcast season of Family Feud, a few set changes and more Steve, which is what the Feud audience loves right now.
GSN currently has the rights to the 2002 to 2006 seasons of Richard Karn's Family Feud and the 2008-09 and 2009-10, the last two seasons of John O'Hurley's Feud. In addition, the first two Steve Harvey seasons are dominant on the schedule.
