My understanding is the original Hogan era through the Andre screwjob wasn't too much different than Bruno though. They had the villain of the month (or however long the angle lasted), and most of them would then work the second tier after Bruno before heading out to another territory. But Bruno himself didn't tour. Hogan era didn't feature him working a squash on Superstars or whatever every Saturday. Sacramento never got Hogan or the A show AFAIR during his prime run. So he was still a main event and kept to just the SNME, an occasional highlight match, WWF's tapes, etc. the NWA champ was the only touring champ that I am aware of, so that worked a lot differently with a typically heel champ working against each territories top babyface and the chase.
Most of my 70s MSG/WWF era knowledge come from John McAdam's Stick to Wrestling podcast so I will admit I am far from an expert.
