Spyglass, Inc. licensed the technology and trademarks from NCSA for producing its own web browser but never used any of the NCSA Mosaic source code. Microsoft licensed Spyglass Mosaic in 1995 for US$2 million, modified it, and renamed it Internet Explorer. After a later auditing dispute, Microsoft paid Spyglass $8 million. The 1995 user guide "The HTML Sourcebook: The Complete Guide to HTML", specifically states, in a section called "Coming Attractions", that Internet Explorer "will be based on the Mosaic program". Versions of Internet Explorer before version 7 stated "Based on NCSA Mosaic" in the About box. Internet Explorer 7 was audited by Microsoft to ensure that it contained no Mosaic code, and thus no longer credits Spyglass or Mosaic.
