It should also be pointed out too, that during the original network runs, and indeed will into the late 1970s, Don Fedderson Productions had a deal with MCA Television (Universal's parent company, whose logo is seen at the end of the credits) to distribute the black and white catalogue of the show. Changes in corporate ownership meant that in the 1980s the syndication deals were renegotiated and Viacom International (who inherited the distribution rights of the Color episodes under it's CBS Films banner and whose corporate title was a hybrid that stood for Video and Audio Communications), then acquired the rights to the the first black and white seasons. Further changes in ownership in the 1990s saw Paramount Pictures being acquired by Viacom, and this is why the Paramount Television logo can now be seen at the end of prints of the color episodes as they are syndicated across the globe. I have been reliably informed by Paramount/Viacom that as the show's distribution company they currently have a moratorium on the black and white episodes and US-domestic TV stations can no longer purchase the color episodes for broadcast after late 2004 as the show has now been removed from US-domestic syndication. The reverse was true in International markets like in Australia where most recently the black and white catalogue is shown on cable television on weekend mornings! Hopefully the situation will change in the medium-term future, allowing all viewers in all markets the chance to see the original episodes again.
