A number of reports from Dan Rowan's "News of the Future" segments came to fruition years later. Notable among them was Ronald Reagan's presidency; he was the governor of California during the original airing of the show, plus the fall of the Berlin Wall.
Both front-running presidential candidates in 1968 were invited to make cameo appearances on the show just before the general election. Richard Nixon accepted and deadpanned, "Sock it to me?" on camera. Hubert H. Humphrey declined. Also, it was because of Nixon's appearance, that many credited Laugh-In with helping Nixon get elected to the presidency.
George Schlatter did not produce the final season, but he won the rights to those episodes in a subsequent court battle. For many years, he neither allowed those episodes to be re-aired, or any clips to be included in retrospectives. On March 13, 2017, Decades TV was allowed to begin airing the final season.
One of the trademarks of the series was the fast cutting that happened in between videotaped segments. Blackouts, one-liners and sketches were edited together in such a way that the show had a very rapid, almost frenzied, pace. This was done before computer controlled editing machines were invented, so much of the show was edited by hand.
One of the show's unusual features was the use of out-takes. If a sketch was flubbed due to a blown line (especially if the cast laughed), it would be included into the show before the perfected take was shown.
The "Cocktail Party" segment often featured uncredited appearances by Playboy centerfold models including Janice Pennington (May 1971), whose appearance was part of her centerfold photoshoot. The models usually appeared as dancers or the objects of Dick Martin's clichéd propositions. Martin married, divorced then remarried playmate Dolly Read (May 1966).
Was revived briefly in 1977, with new episodes featuring Robin Williams and other co-stars, but wasn't picked up. Re-aired during the summer of 1979, after Williams became the star of "Mork and Mindy".
Announcer Gary Owens was seen by many as the inspiration for KORN radio announcer "Charlie Farquharson" on Hee Haw (1969), played by Donald Harron. The interesting thing is, Gary Owens began his announcing career in Mitchell, SD at a AM radio station whose call letters actually were KORN.
Dan Rowan was clean shaven during the initial airings in early 1968. By the first full season, he'd grown a mustache. A few years later, he was sporting a beard, but eventually shaved it off, keeping the mustache until the end of the series.
The show originally aired as a one-time special on 9 September 1967. It was such a phenomenal success that it was given a regular one-hour time slot on Monday nights beginning on 22 January 1968, replacing The Man from U.N.C.L.E. (1964). The program went straight to the top and was the #1 show on television during its first two full seasons, 1968-1970. It began to drop off subsequently as the best talent left to pursue careers in show business, and finally went off the air in 1973.
Another catchphrase of the show was "Here Come the Judge!", beginning when Sammy Davis Jr. guested on the show, and did a tribute to "chitlin' circuit" comedian Dewey "Pigmeat" Markham (who played a judge). It became so popular that Markham was later invited to guest-star on the show. Snippets from his routines were edited into a novelty record, and Baskin-Robbins came out with an ice-cream flavor called "Here Come the Fudge", to cash in on the fad. (Markham later published a memoir, titled "Here Come the Judge!")
