Opera started in 1994 as a research project for Telenor, Norway's largest telecommunications company. In 1995, it expanded to an independent company called opera software ASA. Opera first released version 2.0 in 1996 and only runs on Microsoft Windows. In order to take advantage of the emerging market of Internet connected handheld devices, the project of transplanting opera to mobile device platform was launched in 1998. Opera 4.0, released in 2000, includes a new cross platform kernel that facilitates the creation of versions. Opera is suitable for a variety of operating systems and platforms.
