"The first exposure I had to the Mandela Effect was watching a video about The Berenstein Bears. Various people were commenting that the books that they grew up reading were called The BerenSTEINBears, but now the books were titled The BerenSTAIN Bears. It wasn’t just the new copies that were being printed either. Google searches revealed nothing except the A spelling, including the Wikipedia entry. I had never read these books as a kid; indeed, I had never even heard of them. So, I didn’t think too much about the issue.
