Answer:
Mandela effect
Step-by-step explanation:
This is a phenomenon where some of the population believes an event happened or things looked or were spelled differently. A good example is the death of Nelson Mandela. Many believe Nelson Mandela died while he was in prison, but the reality is that he was released from prison and died much later.
Other examples include:
Sex in the City vs Sex and the City
Luke, I am your father vs No. I am your father
Logo change/name change in Ford or Kit-Kat
One that gets me is chartreuse - I fully believe the color is a of a pinkish hue when it is actually in the green family.
I hope this is what you were looking for.
