OpenType is a scalable format for
computer fonts (also sometimes known interchangeably as "
typefaces"), initially developed by
Microsoft, later joined by
Adobe Systems. OpenType was first announced in 1996, with a significant number of OpenType fonts starting to ship in 2000–2001. Adobe completed conversion of its entire font library to OpenType around the end of 2002.
As of early 2005, there were around 10,000 fonts available in OpenType format, with Adobe's library making up under a third of the total. As of 2006, every major
font foundry and many minor ones were developing fonts in OpenType format.
