"Marc Andreesen was the one who first displayed pictures on the Internet."

I prefer using the internet text-only

"He was a student and part-time assistant at the National Center for Supercomputing Applications at the University of Illinois in 1992, when Internet browsers were not user-friendly and only used by academics and engineers who had access to certain expensive machines named Unix."

Perhaps the author never shared a copy of this article with Burrows before publishing, or maybe The Cardinal had no editor who knew what UNIX meant

This was in 2007. Not long ago, IMHO

I "had access to certain expensive machines called UNIX" before 1992, as an undergradute student, neither an academic nor an engineer

I'm not sure "user-friendly" has much meaning anymore. Today, software that is easy-to-use is routinely "user-hostile"
