So essentially, the Fleischer and Terry characters were split apart? Okay.
I could have sworn some Tex Avery characters, notably Screwy Squirrel, were also in the Fox Movietoon lineup. Has that been retconned out?
The Fleischer characters were actually licensed from other entities. Marjorie "Marge" Buell regained the rights to Little Lulu when Fleischer-Terry and Marge decided to part ways.
Also, Fleischer-Terry was in the middle of another royalty dispute with Ernie Bushmiller when the Nancy and Sluggo shorts weren't having the impact that Bushmiller would've liked.
So basically, Fleischer-Terry actually owned the OTL Terrytoons characters, who were then teamed up with the OTL Walter Lantz characters to form Famous Studios in 1953.
By the way, for those wondering about Howard Post's character Honey Halfwitch, who was voiced by Shari Lewis of Lamb Chop fame, she is owned by Peacock ITTL.
Popeye's rights were still held by King Features Syndicate, who still technically own the character even with Paramount and Universal sharing the multimedia license.
Fox still has Screwy Squirrel. They did have Red and McWolf for a while but when Fox was sold to Disney in 1975, Tex Avery regained the rights to Red and McWolf.
When Tex passed away in 1980, his family sold the rights to Red, McWolf and three shorts (Red Hot Riding Hood, Swing Shift Cinderella and Little Rural Riding Hood) to Turner Broadcasting. Later acquisitions and mergers reunited Red and McWolf with Tom and Jerry, Droopy and Spike and Tyke and together, they came to Paramount.
