In the early 1990s, [[Psion (company)|Psion]] released the [[Psion Series 3]] [[personal digital assistant|PDA]], a small mobile computing device. It supported user-written applications running on an operating system called [[EPOC (operating system)|EPOC]]. Later versions of EPOC became [[Symbian]], an operating system used for mobile phones from [[Nokia]], [[Ericsson]], [[Sony Ericsson]], [[Motorola]], [[Samsung]] and phones developed for [[NTT Docomo]] by [[Sharp Corporation|Sharp]], [[Fujitsu]] & [[Mitsubishi]]. [[Symbian]] was the world's most widely used smartphone operating system until 2010 with a peak market share of 74% in 2006. In 1996, [[Palm, Inc.#Founding and acquisition|Palm Computing]] released the [[Pilot 1000]] and Pilot 5000, running [[Palm OS]]. Microsoft [[Windows Embedded Compact|Windows CE]] was the base for Pocket PC 2000, renamed [[Windows Mobile]] in 2003, which at its peak in 2007 was the most common operating system for smartphones in the U.S.

In 2007, Apple introduced the [[iPhone]] and its operating system, known as simply [[IPhone OS 1|iPhone OS]] (until the release of [[iOS 4]]), which, like [[macOS|Mac OS X]], is based on the [[Unix-like]] [[Darwin (operating system)|Darwin]]. In addition to these underpinnings, it also introduced a powerful and innovative graphic user interface that was later also used on the [[tablet computer]] [[iPad]]. A year later, [[Android (operating system)|Android]], with its own graphical user interface, was introduced, based on a modified [[Linux kernel]], and [[Microsoft]] re-entered the mobile operating system market with [[Windows Phone]] in 2010, which was replaced by [[Windows 10 Mobile]] in 2015.

In addition to these, a wide range of other [[mobile operating system]]s are contending in this area.
