During the process of developing the Apple logo, Janoff came up with the now-iconic outline of an apple in a shape that is quite similar to what we are all accustomed to seeing today.
During the process, he included a bite mark so that it would be clear that the fruit that is portrayed in the logo is an apple and not another fruit with a similar profile, such as a cherry.
This was done so that it would be evident what the fruit that is depicted in the logo is.
