Don Hewitt died last week

TV news legend Don Hewitt dies last week and there have been numerous tributes to him on television. Without him there would be no "60 Minutes," of course, but more importantly he helped create the 30-minute TV evening newscast and the whole idea of the TV "news magazine" format--both of which you could say have spawned our current era of 24/7 cable news. So, are his accomplishments praiseworthy, but the long-term effects the problem?
