Rob Janoff is an American graphic designer, whose most well-known work is the Apple logo design. In 1977, he had his initial meeting with Steve Jobs regarding the logo design for Apple’s brand. During this time, the Apple Computer was still very new, and its first personal computer, the Apple II, was to be introduced with this new logo. Janoff’s idea was to create the logo based on the way apples appeared in real life. It was originally designed with rainbow stripes, signifying the Apple Computer’s ability to show images in colour. The “bite” out of the side of the apple was Janoff’s way of signifying that it was an apple instead of another fruit, along with being a play on words between the physical “bite” and the terminology of “byte.” This logo, though changed only slightly in terms of colour and dimensionality, has remained the same since 1977, and has become one of the most globally recognized symbols.
