Assistant Attorney General Christine Varney said Ticketmaster must license its ticketing software to its major competitor Anschutz Entertainment Group, and must sell off its ticketing subsidiary Paciolan to within 60 days to Comcast Spectacor, which has already signed a letter of intent to purchase the unit, or to another suitable buyer.

The merged entity would also have to submit to a 10-year court order barring it from retaliating against venues that sign pacts with competing ticketing firms.

Varney said, "The Department of Justice's proposed remedy promotes robust competition for primary ticketing services and preserves incentives for competitors to innovate and discount, which will benefit consumers."
