Do you think you know what the original Apple logo looked like? If you said it was the rainbow colored apple with a bite taken out, you’d be wrong. The original logo was Isaac Newton sitting under an apple tree. It was replaced by the rainbow apple in 1976. Apple used the rainbow logo from late 1976 to early 1998, when they replaced it with a simple grey version of the apple.
