History of Blue & Green Message Bubbles


The history of blue and green iPhone message bubbles is tied to the development of iMessage, Apple’s proprietary messaging service. It was introduced with iOS 5 in 2011, offering iPhone users a seamless and free way to send text messages, photos, videos, and more.

The color difference of message bubbles was a visual cue to distinguish between iMessages, which are sent over the Internet, and traditional SMS messages, which use a cellular network.
