Almost 20 years after the release of the first iPhone, Apple customers are still wondering what exactly the 'i' even stands for.

For a long time, all of Apple's products were branded with the letter 'i.' Whether it be the iPod, the iPhone, the iMac, or the iPad, it became an iconic symbol for the company.

Naturally, with so many 'i' products in their inventory, people began to have their own theories.

Users on social media assumed that the famous character referred to the internet, immaculate or even immediate.

Others thought that it just referred to the pronoun 'I,' as in the user themselves.
