Mandela effect?

Hey boys, I'm not sure if this has been suggested yet, but i believe we may have witnessed the Mandela effect in action. I grew up in a world where a young Gus Johnson was pictured in "Extra Cheese Please: Mozzarella's journey from Cow to Pizza" and Nelson Mandela died in jail in the 1980's. The Berenstein bears books were my favorite, and there was a movie called Shazam! where there was a Genie played by Sinbad.

What do you guys think?
