In the 50's and 60's, it was quite common for a TV show to be sponsored by single product/company, and a "brought to you by..." message was often appended to the opening credits/theme. Some series, as collectors of classic clips know, even incorporated the show's stars (both in and out of character) into commercials. (Who can forget the Flintstones smoking Winstons, or Andy Griffith eating his Post Toasties, to name just two of many examples?)
My questions are, first, when more or less did the trend from having a single sponsor to multiple sponsors take hold? And, two, what were some of the last TV shows to feature characters from the show pitching the sponsor's product on-screen?
