Remember "Jesus Christ Superstar"? Andrew Lloyd Webber and Tim Rice wrote a "rock opera" depicting the last days of Jesus Christ, and some found it highly sacrilegious. For my part, I just liked the music.
In the overture Judas Iscariot asks something like "why'd you pick such a backward time in such a strange land? If you'd come today you could have reached the whole nation...Israel in 4 BC had no mass communication".
Interesting thought, that. Never mind the practical problems with finding 3 wise men and a virgin - I'm sure we could have a lot of fun speculating on how Jesus Christ's appearance would have been covered by media like today's. How about the New York Times? The Guardian? Drudge? Bill O'Reilly? Larry King? Instapundit? Andrew Sullivan? The BBC? Atrios?
