Bob Metcalfe invented Ethernet way back in 1973.
Before that, he worked on ARPANET, the forerunner of the Internet.
In addition to being an under-geek, Bob is also a master salesman.
Let me quote something about Bob from Emanuel Rosen’s excellent book "Anatomy of Buzz."
"Bob Metcalfe, father of Ethernet and founder of 3Com, told Scott Kirsner how young MIT engineers often came to him for advice.
After they go through his six-story town home in Boston’s Back Bay, many of them say something like "Wow! What a great house! I want to invent something like Ethernet."
At this point Metcalfe has to sit down and explain, "No, I don’t have this house because I invented Ethernet. I have this house because I went to Cleveland and Schenectady and places like that. I sold Ethernet for a decade."
OK, with that as a background, listen carefully to what Bob has to say about video and salesmanship, especially in the post script at the very end of the interview. Profound stuff.
