When this began it was called "The Mandala Effect" referring to the buddhist pattern which some say transcribes the nature of reality. I've somehow sidled into a dimension where it's called the "mandela" effect.
Also, we used to spell "Malcolm" as "Malcom"- younger me was very disturbed to turn on the TV and find that the show was now called "malcolm in the middle" rather than "Malcom in the Middle"
