Keep Circulating the Tapes: 104 shorts were made. Only a fraction were ever released on VHS, and the tapes have been out of print for years. Some of them can be found on YouTube.
Recursive Adaptation: The episodes in this series were eventually rewritten as picture books.
Troubled Production: The first animated series entered production by Milktrain Production in 1977, with financial investment from firm Lafferty, Harwood, and Partners. However by 1979 only 32 of the agreed-upon 104 shorts were completed, due to Milktrain running out of money. In order to secure additional funding from Lafferty they had to agree to let them take over the production completely. All 104 shorts were finally completed in 1982.

Baby Name Trend Starter: In Japan, this show caused the name "George", or as it's spelled in Japanese "Joji", to increase in popularity. It's gotten to the point where fictional characters in anime have also been given the name George!
Channel Hop: Five years after the last new episode aired on PBS, the show returned with new episodes (well, new to the US; see The Shelf of Movie Languishment and Short Run in Peru below) on the Peacock streaming service in July 2020, before airing on PBS three months later.note Unlike fellow PBS Kids show Sesame Street, which uses a similar method with premiering episodes on HBO first, new episodes of the show are exclusive to the 24/7 PBS Kids channel and said channel's livestream, but PBS affiliates only air older episodes.
Jim Cummings, an American, voices Chef Psighetti, who's Italian.
Marco is Spanish, yet is voiced by Grey DeLisle, an American.
"King Doggy" has Frank Welker, George's voice actor, also voicing a Royal guard. Another episode has him voicing an obedience school teacher. He used a British accent for both of them even though he's American.
In "King Doggy", Kari Wahlgren, an American, also uses a British accent for the princess.
The show's streaming deal with Hulu was why the show did not appear on the 24/7 PBS Kids channel when it launched in January 2017. However, it eventually started airing there in October 2020.
The show would later fall under this trope again when Peacock gained the streaming rights to new episodes of the show. On Samsung's PBS Kids channel, an error message is displayed if one turns on the channel while Curious George is airing, redirecting them to use the PBS Kids app. By June 2023, even the PBS Kids app restricted livestreams of the show.
Short Run in Peru: As mentioned above, Canada was one of the first countries to air seasons 10 to 12 before they were released in the US, with seasons 10 and 11 airing weekly from September to December 2018 and May to August 2019 respectively, and season 12 airing throughout the month of February 2020.
