* HeyItsThatVoice: The original sidekick/announcer was a young man named [[Series/MatchGame Gene Rayburn]], and the sidekick to Jack Parr's era was [[Series/{{Concentration}} Hugh Downs]].
* KeepCirculatingTheTapes: With selected episodes officially being released on DVD, Carson Productions is becoming increasingly insistent on having unauthorized Website/YouTube Carson clips removed from the site.
** To their credit, Carson Productions has been releasing a good number of complete episodes (usually the mid 70's 90 minute episodes) on YouTube for free viewing.
** Thanks to the 2010 ''Tonight Show'' debacle, NBC will never release any [=DVDs=] or digital downloads of ''The Tonight Show With Conan O'Brien''. In fact, the only acknowledgment of the show at ''all'' as of late seems to be a split-second showing of O'Brien's name as part of a list of past ''Tonight Show'' hosts that was seen during various promos for Jimmy Fallon's then-upcoming premiere.
* MissingEpisode: Much of Steve Allen's tenure is gone, although the premiere seems to exist.
-->'''Allen''': In case you're just joining us, this is ''Tonight'', and I can't think of too much to tell you about it, but I want to give you the bad news first: this program is going to go on ''[[http://www.youtube.com/watch?v=n8AYUfBt1dE forever]]''.[[note]](Okay, so he was talking about the show's night-by-night length, but still...)[[/note]]
** Much of the first 10 years of Carson's version, due to tape reuse. 1972-92 are intact.
** On ''The Tonight Show With Conan O'Brien'', the episode with Teri Hatcher as a guest was never aired; it was never finished because Conan was rushed to the hospital for a concussion that he suffered during a foot race with Hatcher.
