For whatever reason, and basically with no advanced warning, the AT40 schedule changed this weekend. The 6am Eastern Saturday broadcast has been eliminated, as has the noon, and so apparently programmers split the difference and made the Saturday broadcast 9am. The Sunday broadcast moves from a 9am start to a noon start, and the midnight Sunday/Monday broadcast, and the Thursday "Wheel of Casey" (a random show that can be from any date, any year in the 70s) remains intact.). This caused protests from the sizable group of people who "live tweet" along with the noon Saturday broadcast, which sometimes has made AT40 a trending topic on Saturdays. That's not the only change on 70s on 7. ’70s on 7 Gets Poppier; The Drive Gets Even Bigger - RadioInsight
