@aral The salient point is that although both companies’ #browsers did not appreciably derive actual mechanisms (code) from #NCSA, they would not exist without #NCSAMosaic’s initial research, design, and refinement.

So both @kpeace and @keithzg are correct depending on one’s perspective.

@kpeace @keithzg @aral Yes, but no.

Both companies’ web #browsers trace their origins to #Mosaic by The University of Illinois Urbana-Champaign’s National Center for Supercomputing Applications (#NCSA).

#Netscape Navigator was a rewrite of #NCSAMosaic by its co-creators.

#Microsoft #InternetExplorer was based on code licensed from Spyglass, a #Mosaic trademark and technology licensee who had supposedly only used the original code sparingly.

With the 30th anniversary of NCSA Mosaic's 1.0 this week, I'm reminded that I was one of the earliest, possibly only the second person, to have Mosaic on a box at all of JMU...

...and I got it from (I presume) the first one to have it, @dwenius
