The Mandela Effect Effect 

Due to the Mandela Effect which was popularized in 2010 people discovered Nelson Mandela was actually alive and did not die in prison in the 1980s. He later did die in 2013. Because the Mandela Effect is more commonly known than the effect's namesake, many people believe he is still alive.
Nelson Mandela actually died in 2013; you are the victim of the Mandela Effect Effect.

The Mandela Effect 

Contrary to popular belief. The Mandela Effect has nothing to do with time travel or multiple alternate universes colliding.

The Mandela Effect is the recollection of events that never occured. (eg: Shazaam featuring Sinbad. It was actually Kazaam featuring Shaq.)

The name of the phenomena is derived from the belief that mandela died in 1991 in prison.
"Remember Sinbad in Shazaam? No. It never existed. It's the Mandela Effect"
