The suit began on May 18, 1998, with the U.S. Department of Justice and the Attorneys General of twenty U.S. states (and the District of Columbia) suing Microsoft for illegally thwarting competition in order to protect and extend its software monopoly. In October 1998, the U.S. Department of Justice also sued Microsoft for violating a 1994 consent decree by forcing computer makers to include its Internet browser as a part of the installation of Windows software. While the DOJ was represented by David Boies, the States were separately represented by New York Attorneys General Alan Kusinitz, Gail Cleary and Steve Houck.
