I've heard of Enron and WorldCom.
(edit follows 'cause I hit the button too soon)
Adelphia, the nation's sixth-largest cable company with 5.7 million subscribers in more than 30 states, filed for bankruptcy protection last month.By way of comparision, NYC had 8 million people + living in the city itself.
Is there a huge difference between 6th place and 1st or 2nd place?
