Whatever Fox is paying American Idol meanie Simon Cowell, it's not enough. Fueled by two highly-rated editions of Idol (as well as a little show called Joe Millionaire), Fox was the most-watched network last week — the first time it has scored such a feat on the strength of its entertainment programming alone. In other ratings news, the Sunday premiere of Dragnet on ABC drew 13.3 million viewers while NBC's competing Kingpin had 12.5 million.
