No idea, but “Red, White and Blaine” from Waiting for Guffman has.
The ankle monitor sprang from a Spider-Man comic strip. The Kingpen had attached one to Spider-Man, and the inventor of the real one took his idea from that.
Not research but I just read the book the team put out about their history. The “group” first appeared as a spoof on a comedy tv show. But except for a couple of appearances to get ready for the movie, they never were a band prior to that.
Dick Tracy had a two-way wrist radio and later a two-way wrist television. Both have existed in some form since.
Similarly, many of the flip phones of the 2000s closely resembled the communicators from TOS era Star Trek.
You mean what TV Tropes calls Defictionalization?

Has nobody mentioned a leg lamp yet? It obviously existed in that cinematic world and you can buy them in several sizes now.
Leg lamps were certainly popularized by A Christmas Story, but did they not exist at all before that?
Good question. In Gene Shepherd’s stories that were the basis for A Christmas Story, the Old Man won the lamp in a contest sponsored by Nehi soda (Nehi’s logo was a leg and stocking). But did Nehi ever sell or give away actual leg lamps as a promotional item, or was that just Shepherd’s invention?
Puppers Beer, the fictional brew from the hit comedy series Letterkenny, is an actual, officially licensed product now. It was originally a novelty created just for the show, but due to high demand, it was brought into the real world.
It’s a 5% ABV golden lager produced in Canada by Labatt Breweries.
I saw the “Unwigged and Unplugged Tour” in 2009, it was a really fun show. Guest, McKean and Shearer played Tap songs, Folksmen tunes and told stories. One of the highlights of was a screening of “Tonight I’m Gonna Rock You Tonight” performed by a Lego Spinal Tap band.
Sadly that part of the show didn’t make it to the DVD because Lego didn’t think the video was “age group appropriate” .
I’ve read that Robert A. Heinlein invented the waterbed in fiction. No clue whether true.
In Home Alone, Kevin had a toy recording device called a Talkboy that he used a few times to fool adults. At the time, it was just a prop. But after the movie came out, it became an actual toy you could buy.
Here’s another thread about that very subject, with a similar but not identical title:
Scooby Snacks.
Human and Dog varieties.
(Yummy)
Not true. Versions of waterbeds had existed for 100 years before Heinlein.
He didn’t invent waldoes either.
Never mind.
And I can remember the Everlasting Gobstopper.
When I saw Peter Frampton in 2002 people were shouting out requests for “Do You Feel…”, so he teased the audience by pulling out a Talkboy that had a a couple of talkbox phrases from the song and held it up to his vocal mike. Got a big laugh from everyone.
Aw, darn. But thanks!
Mexico now has a Dia De Los Muertos parade because it was depicted in a James Bond film.
