Even more so when you consider how hard Disney is still pushing all things Mickey Mouse here in 2026 and how much Hanna Barbera is not pushing anything Flintstones now and has not been for decades.
I thought Willy Wonka products were still around but it seems it was discontinued in 2018.
He may have used them, but the Aston Martin was never primarily a promotional gimmick based on the series.
Peter Pan peanut butter was named in 1928. I don’t know if kids nowadays are watching Peter Pan or not (Disney is probably using him as a character in some show somewhere).
Actually, according to Wiki Flintstones Complete comes in three varieties: chewable, gummy and sour gummy.
But they were clearly branded for the show, so that kids who were into the show would be into them.
The Aston Martin was not (there was a limited edition 007 model released in 2020 but it did not outlast the film)
What about Baby Ruth candy bars? They’re still around.
If you believe Nabisco’s official story, they are named after Ruth Cleveland, who died in 1904. If you are more cynical, they are named after Babe Ruth, who died in 1948.
And after the first-run shows on ABC ended in 1966, the series was ubiquitous in syndication in the U.S. through the '70s, at least; I know that I watched it regularly in that era, though I was only a year old when the network run ended.
That’s named for someone not a promotion for a specific show. If that counted it would put the answer back a few millennia
Concur, I remember watching the Flintstones every day after school throughout the 70s. And eating Flintstones vitamins. The crunchy chalky ones.
Ajax cleaner, or something earlier than that?
The concept has been around for more than a hundred years. Felix the Cat, Popeye, Little Orphan Annie…they all had branded products but none of them as long-lasting as those Flintstones products.
“Lamb Chop” dog toys are still immensely popular decades after The Shari Lewis Show and Lamb Chop’s Play-Along went off the air.
Popeye canned spinach is still a thing https://www.popeyespinach.com/
Looks like the spinach brand license for the character started in 1966. Popeye was first animated in 1933.
I swear there was some recent show/movie that made a “There’s a baseball player named after the candy bar?” joke.
Well blow me………..down!
I have never heard of Popeye Spinach (the brand) until now!
You must not be a regular in the canned spinach aisle, then! 
I knew it was a brand, but I hadn’t seen it in decades.
Then again, we mostly buy frozen and occasionally fresh spinach, so I guess I’m no expert. I’m not sure I’ve ever bought a can of spinach.
To be fair I’ve never bought canned spinach either, but the can design sort of … pops … out at me when I’m scanning the canned veggies.
The general consensus seems to be that the Curtiss Candy Company (the original manufacturer of Baby Ruth) was trying to capitalize on the huge popularity of the baseball player, but didn’t name it directly after him, because they did not want to have to pay him royalties for use of his name.
So, the company story, for over 100 years now, is that it was named after the daughter of President Grover Cleveland, Ruth, who was indeed, when she was born, a popular celebrity. However, that story doesn’t hold much water, as the candy bar was named that (it was a refashioned and renamed version of an earlier bar) almost 30 years after “Baby Ruth’s” celebrity, 16 or 17 years after she died (she was a sickly child, and died at age 12), and 24 years after her father left the White House. So, the idea that it was named after someone whose fame was already 20-ish years out of date seems unlikely.
But, even now, Nabisco (the current owner of the brand) sticks with that story.
