Actually Jim Bakker and Tammy left CBN and TV 27 in the late winter of 1973 right after the station expanded from signing on at 2 pm and off by Midnight to signing on at 10 am and off at 1 am. Until then they were 700 Club from night before at 2 pm, a mis of family dramas and comedies till 5, Bugs Bunny at 5, New Zoo Revue at 530, Jim & Tammy at 6, a couple secular shows at 7, Christian shows at 8, and 700 Club live at 11. When they expanded to a 10 am sign on shows like Beaver, Flipper, Lassie, Fury, Roy Rogers, Bugs Bunny, and a couple others were joined by Popeye, Little Rascals, Dennis The Menace, Gilligan's Island, Father Knows Best, Riflemen, and a few others as well as a few hundred old movies. The GM decided at the time to only have Jim & Tammy do a weekend show and host the kids shows, and put Gilligan's Island and another sitcom on at 6 pm weeknights. Bakker insisted on remaining on his timeslot. Pat Robertson refused to override the decision and agreed to move the station into a general entertainment format and an expanded broadcast day. The Fall of 73 shows liek Flintstones, Star Trek, Dick Van Dyke, Hogan's Heroes, Get Smart, Yogi Bear, and a bunch of others were added and the station began 630 AM sign on with cartoons till 9, sitcoms till 10, 700 Club now live at 10 AM not PM, New Zoo Revue at noon, westerns till 230, cartoons till 5, sitcoms till 7, drama shows till 9, 700 Club at 9 PM, and a mix of old movies and drama shows late at night. By 1976, WYAH had Brady Bunch, Odd COuple, I Love Lucy, and eventually Tom & Jerry. Bakker felt that an expanded broadcast day should mean more time for his show, not less. He and Tammy went to California and joined Paul Crouch to launch TBN in march of 1973.
How he began PTL was another story. Ted Turner's 36 WRET Charlotte had been signing on at noon. Turner wanted to add a morning cartoon block so he did from 7 to 9 am. because mid mornings were a hard sell, he sold the 9 am slot to Pat Robertson for his 700 Club, and filled remaining time with public affairs shows till noon. This began around 1971. Movies aired at noon, comedy shows till 3, cartoons till 5, comedy shows till 7, drama shows till 9, a movie at 9, and a mix of drama shows and movies late night till about 1 or 2 AM when the station signed off. Turner had 17 WTCG Atlanta (now WPCH eventually WTBS). That station focused on movies, sitcoms, drama shows, and cartoons and was on the air about 20 hours a day. Meanwhile CBN signed on Channel 46 WHAE in 1971. That station was on the air 4 hours a day with only Christian programming. By 1972 the station was on the air 6 hours a day with an hour of secular shows (Fury and Of Land & Seas), and Christian the rest of the day. Turner had no problem with this. Robertson swore he had no plans to change formats on WHAE. Meanwhile TV 27 WYAH was evolving into a full blown independent station and completed the transition in Fall of 1973. In Dallas CBN had a 6 hour a day station on TV 33. A secular station across town on TV 39 was donated to CBN with programming included in 1973, of at which time 33 KXTX moved to TV 39 and combined assets and also became a full time independent that fall. Still as late as 1974, 46 WHAE Atlanta was still only on the air 7 hours a day with Christian shows over 5 hours a day. That Fall, though WHAE expanded to 14 hours a day with Secular shows 8 hours a day from noon to 8. Ted Turner was livid. He claimed Atlanta could only support one independent station and his WTCG was making only modest money and with 46 competing, Channel 17 would lose money. Out of Anger, he dumped the 700 Club in Charlotte and reverted 36 WRET to an 11 AM sign on again dumping the morning cartoons at least temporarily. Turner needed a show to replace 700 Club to resume 6 AM sign on so in the fall of 74 he approached Jim Bakker and offered to give him the time in return for a percentage of his donations. Jim & Tammy bakker left TBN fall of 1974. Turner would lend Jim Bakker a studio at WRET Charlotte and in the late fall of 1974 PTL Club was born. Bakker eventually raised enough money to get his own studio and more in a couple years. So PTL began as a result of Ted Turner dumping 700 Club on his WRET 36. WRET incidentally got NBC affiliation in 1978 when WSOC dumped NBC for ABC. 18 WCCB lost ABC and was left an independent and took 700 Club and some of WRET's shows. Turner sold WRET to Westinghouse and the station became WPCQ in 1980 to fund CNN. TV 36 was sold to renaissance in 1987 and to Providence Journal in 1990 and renamed WCNC, then sold to Belo, thene merged with gannett.
