Hotmail initially ran under Solaris for mail services and Apache on FreeBSD for web services, before being partly converted to Microsoft products, using Windows Services for UNIX in the migration path. By December 1997, it reported more than 8.5 million subscribers. Hotmail was initially backed by venture capital firm Draper Fisher Jurvetson. The name "Hotmail" was chosen out of many possibilities ending in "-mail" as it included the letters HTML, the markup language used to create web pages (to emphasize this, the original type casing was "HoTMaiL"). It was commercially launched on July 4, 1996, symbolizing "freedom" from ISP-based email and the ability to access a user's inbox from anywhere in the world.
