Lots of clips that a bot probably gathered, with the Johnny Carson clips obviously from more than one decade, and a bit of Home Alone 2 from 1992 got in there, too. I looked at another video on what were supposedly typical '70s houses, and the YT comments pointed out some details were typical of homes decades earlier.

This channel is VERY monetized. It sells its own merch and also links to tons of '70s style products on Amazon (possibly bot-selected), gets a cut from those sales. The YT info about the channel has a link for "business & sponsor inquiries."

They apparently didn't get any permission for the content, all those old ads and stuff, probably ripped off from other YouTube videos, since there's the standard notice saying "The materials in this video are intended for entertainment purposes and comply with fair use guidelines. No copyright infringement is intended. If you are the copyright owner or represent them and have concerns about the use of any material in this video, please contact us..."

Sigh.

One thing that always seems especially weird about these videos is having an AI voice reading an AI-written script trying to evoke nostalgia in humans.

I know there are older nostalgic videos on YouTube with clips of commercials and TV shows carefully selected by humans who actually remembered them. Videos where you hear the commercial instead of an AI voice talking nonstop, telling you how you supposedly felt then.

But I just checked, and you already have to scroll past lots of recent AI-generated nostalgia videos to find human-curated compilations from more than a few years ago. And the AI videos are being generated so fast that they're starting to bury what's human-made. Like this video from 2017:
