A drama series on the
Fox network, premiered
September 20, 2002.
The lead character doesn't know who he his, and thus adopts the "John Doe" moniker. He woke up naked on an island near Seattle and has no memories of himself, his life, his personal identity. He has only an odd brand on his right breast to provide clues.
He does, however, seem to know just about everything else. No, really, everything. He apparently is channeling E2, Google, the Encyclopedia Britannica, and Ghu only knows what else. (The character has been shown to have instant access, via only his brain, to DMV records, advanced chemistry texts, and the White Pages.)
