 In popular use, web desktops are sometimes referred to incorrectly as web operating systems or simply WebOS.In the context of a web desktop, the term Webtop was first introduced by the Santa Cruz Operation (SCO) in 1994 for a web-based interface to their Unix operating system.This application was based on the provisional application entitled "The Adaptive Internet Protocol System" filed Nov. 13, 1997, serial number 60/065,521 and is the U.S. patent for the technology used in the Tarantella Webtop.
