In Los Angeles, televised wrestling mostly took place from the venerable Olympic Auditorium, still standing at 18th & Grand in Downtown L.A., and it's now used mainly for film shoots and is owned by a Korean church.
Among the many ring stars seen were Freddie Blassie (who at one point nearly owned L.A., he was so huge), the Destroyer, Lou Thesz, Don Leo Jonathan, Bobo Brazil, Bearcat Wright, the Torres Brothers, Cowboy Dick Hutton, Gorgeous George, Iron Mike Mazurki, Count Billy Varga, Mr. Moto, the Great Togo, Tricky Ricky Starr, Hard Boiled Hagerty, who acted in films and TV shows under the name H.B. Hagerty, and the midget legend Sky Low Low, among many, many others I could name.
I admit it - I was big fan.
The announcer was the legendary Dick Lane, who created the exclamation "Whoa, Nelly!". Keith Jackson admitted he "borrowed" the phrase from Dick Lane. In an interview after he retired, Lane explained that Nelly was a roller derby skater who once had trouble keeping her balance after being whipped too hard out of the pack in a match he was broadcasting. As she was desperately trying to stay upright and flailing her arms, Lane instinctively said "Whoa, Nelly!", and a catch-phrase was born!
After wrestling moved from KTLA, channel 5 to KCOP, channel 13 around 1971, they stopped televising from the Olympic and moved it to the channel 13 studios on La Brea. The main stars at the time were Blassie (still), Victor Rivera, John (the Golden Greek) Tolos, and a young villian named Roddy Piper, who loved to torment Freddie Blassie.
FYI: KTLA's coverage of wrestling was awarded the very first sports Emmy in 1948.
