Internet Explorer 1 made its debut on August 16, 1995. It was a reworked version of Spyglass Mosaic, which Microsoft had licensed, like many other companies initiating browser development, from Spyglass Inc. It came with Microsoft Plus! for Windows 95 and the OEM release of Windows 95. It was installed as part of the "Internet Jumpstart Kit" in Plus!. The Internet Explorer team began with about six people in early development. Internet Explorer 1.5 was released several months later for Windows NT and added support for basic table rendering. However, by including it for free on their OS, they did not have to pay royalties to Spyglass Inc., which resulted in a lawsuit and a multi-million USD settlement.
