Yes Family Channel when sold to Fox and again to Disney/ABC had to keep triple runs of 700 Club.
Now about 61 WRIP/WDSI - Technically they were not a religious station. They were technically a low budget independent. They started out with an ambitious Movie format but when financially failing in 1973 they were sold to an owner that needed to turn a profit so they opted to offer blocks of time for sale so they sold the time to anyone that could buy it. It just happened to be religious groups that bought most of the time. By 1979 WRIP TV was selling all but an hour a day to outside sources, nearly all religious. Their secualr shows were ultra low budget.
Finally in September of 1981, WRIP began adding several hours a day of barter shows and a few low priced syndicated shows. They went from an hour a day of secular shows to 3 hours a day of them. By early 1982 they were up to 6 hours a day of entertainment as they acquired movies, more sitcoms, and some drama shows. By the SUmmer of 1982 they ran about 10 hours a day of entertainment and 10 hours a day of bought time which was still nearly all religion. Then the station was sold in january of 1983 and renamed WDSI and went to about 15 hours of entertainment and 6 hours a day of religion.
By 1985 they were down to only a couple hours a day of religion and by 1986 all but a couple hours a day of religion was gone. WDSI wound up a typical Fox affiliate which they are today.
WPCB 40 Pittsburgh ran hardly any secular shows. If they did so it had to have been before 1983 maybe. Now in Greenville SC, 16 WGGS had secular shows about 5 hours a day with religion occupying 10 hours a day. By 1980 when WGGS was 24 hours they ran religion till 7 AM, secular 7-830 AM; religion 830 AM to 1 PM, Secular 1-7 PM, and religion the rest of the night. From 1982 to 1986 the secular shows gradually fell off the schedule and by 1987 WGGS was religious all but one hour a day. They remained like this until 1990 when they picked up an hour of cartoons a day from 2-4 PM; By 1993, WGGS was secular 3 to 6 PM weekdays with a syndicated Disney cartoon (that was no longer part of Disney Afternoon), some syndicated barter Hanna Barbara cartoons, Wonder Years, Gilligan's Island, and Ozzie & harriet. Then as Channel 40 WFBC seperated from WLOS in 1996 and 62 WASV came on as a UPN/WB independent in 1997, WGGS moved back to a nearly all Christian format by 1999. Their DT-2 runs Secualr shows about 1/3 of the time, mostly public domain stuff.
Carolina Christian's sister stations in Columbia SC and Myrtle Beach ran Secualr shows a third of the time. WCCT 57 was sold to a secular owner in 1987 and became a Fox Independent station. WGSE Myrtle Beach remained 1/3 secular and 2/3 Christian until 1990, when they went nearly all secular under Carolina Christian TV. In 1990 they ran Niteline at 5 AM, 700 Club at 6,a nd then Secular shows all day till 10 PM when they ran Niteline and then at 11 PM back to secular shows again. The secular shows by 1991 were all barter including cartoons, some sitcoms, some game shows, court shows, and talk shows. WGSE became a WB affiliated indie in 1995 and in 1998 they were sold to a secular owner and are now a Fox affiliate. It seemed wierd that in 1990 Carolina Christian had a nearly all Christian station in Greenville SC while in Myrtle Beach had a nearly all secular station. These stations were polar opposites of each other. Carolina Christian also launched another station in Columbia SC in 1996 which took both UPN and WB programming, and barter syndicated shows. That station was religious about 5 hours a day. They too have since been sold and I believe they are a CW station today.
