Vint Cerf and Bob Kahn's letter to Declan McCullagh defending Gore, who was primarily responsible for spreading the "invented the internet" meme via articles in Wired, dates from 2000 and is here:
(as much as the internet can the invention of anyone, it's the invention of Cerf and Kahn, who invented TCP/IP).
As they say, a lie can go around the world and back while the truth is lacing up its boots. McCullagh, whose libertarian sympathies were never much of a secret, never apologized for his role in smearing Gore. He's now chief political correspondent for CNET.
