Today I read in an unimpeachable source that until 1989, Oscar presenters had always opened the envelope and said, "And the winner is . . . ." In that year, however, someone pointed out that calling one of the nominees a winner implied that the others were, well, losers. So from that day forward, Oscar presenters have said, "And the Oscar goes to . . . ."
Of course, as we all know, it's an honor just to be nominated.
