I tried to tune in to MG78 just before 10:30 PT this morning, only to see the tail end of Hollywood Showdown, followed by J! at 10:30 and MG90 at 11:00. These shows had been airing at 7, 7:30 and 8. (Even though the "up next" block that just came on listed MG90 for "11 am ET / 8 am PT".)
I know a West Coast feed had been rumored... did they throw the switch today? If so, Friday is an odd day to do it. If there's any announcement on GSN's site about it, I didn't find it. (Which of course is not surprising.) And if they did, the "up next" times don't reflect it.
