Raymond Burr had been hounded by CBS Network executives about staying for a 10th Season. CBS was also getting hounded by lots of the Show's fans, including closed door meeting with "Perry Mason" executive producer Gail Patrick Jackson, who was considering moving the Show to another network, possibly ABC or NBC. CBS was desperate in trying to entice Jackson, Burr & several others in coming back to the CBS network.....
Jackson announced she would call a press conference in a few days, but confirmed "Perry Mason" would be coming back for a 10th Season though, but as to whether they'll remain with CBS was unknown.......
