Despite being a heavily decorated series (http://www.sitcomsonline.com/boards/showthread.php?t=281785) is it true that it was not really a big success in syndication (https://en.wikipedia.org/wiki/The_Mary_Tyler_Moore_Show#Syndication) (at least until Nick at Nite started airing it around 1992) ever and not even a giant DVD success story? I heard that the show probably wouldn't have had all the seasons released if Oprah Winfrey didn't get involved, heavily promoting the show.
