Twenty-five years ago a couple of guys switched a then-obscure military agency over to a new computer standard called TCP/IP. The switch suddenly made it possible for small experimental computer networks all over the country to talk to each other — and that made the Internet possible.
The obscure military agency was DARPA — the Defense Advanced Research Projects Agency. And one of those guys was Vinton Cerf, who is commonly called "The Father of the Internet." He talks to Andrea Seabrook.
