It has been 16 years since Apple CEO Steve Jobs introduced the first iteration of the iPhone to the world.

At the Macworld expo, Jobs introduced a device that would change everything. At the time, Jobs said that Apple was going to "reinvent the phone" and that it would have a multi-touch display with no physical keyboard.

Jobs described the iPhone as an iPod with touch controls, a phone, and a breakthrough internet communications device, three distinct areas that no device at the time was able to tackle all at once. The original iPhone had a 3.5-inch screen, a camera, and a body.

Since the original iPhone, Apple has continued to update it with new features. The first significant redesign of the iPhone came in 2010 with the release of the iPhone 4. The introduction of the iPhone 4 marked a turning point in the history of the device, as it offered an entirely new design with flat edges, a brand new display, and more.

Two years later, the iPhone 5 marked another redesign for the phone, making it taller with a larger display, the A6 chip, a thin design, and more.

Touch ID and Face ID are just two of the innovations that Apple introduced in the years that followed.

Fast forward to today and there are four different models in the lineup. An all-screen display with no Home Button, facial recognition, 4K video recording, a 48MP camera, Dynamic Island, and all the features are present in the current-day iPhones.
