I'm happy for the route from NBC in May 1971, mainly in search of the slot nite 9pm EST, Friday. If I recall that the orientation of clock with an 8 "Sanford & Son" began, followed by "Chico and the Man, who was 8-9pm slot, the time and place --- 10 clock Friday nite was followed by the Police Woman. " I thought the slot was 9pm hour of of "The Rockford Files" - but I understand that this program only began in 1974. The question that I tried to answer more than 30 years, one will find inside and outside. It was Friday, May Prom nite nite nite I do not mean to go and I stay at home and watched television. I would find every means to get how this problem will provide the best response - or - someone to tell me that I finally got this burning question put to rest.
