Ted Koppel, the former ABC newsman who got his big break when Iranian Islamic fundamentalists took Americans hostage during the 1980s, has been wooed by Al Jazeera, the 24-hour satellite news channel that many see as the voice of the Islamic world. Koppel Friday told reporters attending the Television Critics Association conference in Los Angeles that the Arabic TV channel approached him and his long-time producer Tom Bettag about joining Al Jazeera, but quickly added, "I don't think Tom and I entertained it more than 38 seconds."
