Berenstain/Berenstein Bears

Another popular Mandela effect is the Berenstain/Berenstein conspiracy theory. Growing up in the early 2000's you have read, or at least heard of the Berenstain Bears. I have always thought it was spelled Berenstein Bears which I later found out I was wrong. This bear family's last name is Berenstain not with a "e", but with an "a". Many people thought the same as me, so everyone was looking at their books to see if maybe it was a mistake. People theorize that sometime during the 10 years that no one was very big on the Berenstain Bears they changed it to a "a", but that theory was turned down because of the authors of the books last name is Berenstain, and has always been Berenstain. During the 1800's the Berenstein's came over to America, and had to change their name to Berenstain because people could pronounce it better. I still believe it to be spelled Berenstein along with many more people, but maybe we are all completely wrong, and its been "a" all along.
