Tonight GSN shuffles their Sunday night lineup to add Pat Finn's Shop 'Til You Drop from 7pm to 9pm (Eastern). These episodes of Shop 'Til You Drop are "New to GSN", which means they have never been seen before on the network and really have not been seen on television since they aired over a decade ago.
There are no other surrounding schedule changes. Steve Harvey's Family Feud airs from 5pm to 7pm (ET) and The Newlywed Game (Shepherd) from 9 to 11pm (ET).
Shop 'Til You Drop still airs weekdays at 4pm (ET) and 4:30pm (ET).
I have to give GSN credit for putting a lot of advertising into the decade-plus old game show. GSN realizes they cannot live off Family Feud forever, which is still #1 in ratings week after week. Between pre-1990's acquisitions, the recent additions of 1 vs. 100 and Deal or No Deal back to the schedule plus their efforts at the Minute to Win It revival, GSN has gone back to their roots, for now. Let's hope it can stay this way: Strictly fan favorite game shows.
