I've watch little house for years. Now I believe this was in the mid to late 80s little house became E/I programming-educational and informative. I just started my radio career and my mentor of sorts was the General Sales manager of the local CBS TV station while talking about media stuff he said we have LHOTP we can air it on the weekends but can't air the same episode that run during the week on rge local NBC Station. I asked how both station that were not 50 miles from each other to air the show on syndication. He said Michael Landon made the program E/I and that rule does not apply He says he did it for more money in his pockets for syndication fees
