The Internet Explorer project was started in the summer of 1994 by Thomas Reardon, who, according to the Massachusetts Institute of Technology Review of 2003, used source code from Spyglass, Inc. Mosaic, which was an early commercial web browser with formal ties to the pioneering National Center for Supercomputing Applications (NCSA) Mosaic browser. In late 1994, Microsoft licensed Spyglass Mosaic for a quarterly fee plus a percentage of Microsoft's non-Windows revenues for the software. Although bearing a name like NCSA Mosaic, Spyglass Mosaic had used the NCSA Mosaic source code sparingly.
