The inspiration for the bitten iPhone logo comes from the 2001 British movie Enigma.

A widely circulated theory about the Apple Logo is that Apple Computer uses the bitten apple as its trademark to commemorate the great pioneer in the field of artificial intelligence-Alan. Turing is actually a misinformation.

The source is the 2001 British movie Enigma, in which a fictional plot about the relationship between Turing's suicide and the Apple logo was misrepresented by some members of the public and the media.

Extended information:

In 1976, Jobs decided to re-appoint Rob Janov, the art director of the Regis McKenna public relations company, to redesign a better logo to match the release of Apple II.

So Janov started making a black and white silhouette of an apple, but he always felt that something was missing, "I wanted to simplify the shape of the apple, and there was a bite on one side - a?byte, right? , in case the apple looks like a tomato," explains Janov.

Javov then added six colorful, horizontal bars, thus completing the colorful Apple logo we know today. In 1998, a new translucent plastic texture logo was applied to new products iMac and G4 Cube, making the logo appear more three-dimensional and fashionable.

The reason for the logo change this time is that the new products all use transparent material casings, which were changed to match the texture of the new products. Black logos also appeared almost at the same time. Most of them appeared on packaging, products or contrasting colors that needed to be highlighted in order to coordinate with product promotion. Apple's monochromatic logo is still used today.
