CBS is making an interesting move with two longtime competition shows. Both “Survivor” and “The Amazing Race” are expanding from one hour an episode to 90 minutes. The shows will take over the Wednesday night schedule with “Survivor” airing from 8-9:30 pm ET while “The Amazing Race” will follow from 9:30-11 pm ET. “Survivor 45” is currently filming in Fiji and “The Amazing Race” season 35 was shot late last year.
