COMPANY TOWN : Ticketmaster Names Midwest Exec to Head New Ticketing Company

Ticketmaster is restructuring its operations, putting its ticketing business into a newly formed company and promoting a Chicago-based executive to run it day to day. The company is forming Ticketmaster Ticketing Co., and it named Terry Barnes, head of its Midwest ticketing operation, president and chief operating officer. Frederic D. Rosen, who heads Ticketmaster, will be chairman and chief executive of the new unit, but is expected to relinquish daily operational duties to Barnes so he can work on acquisitions and other ventures to expand the company.

Separately, Ticketmaster named Claire Rothman, Marla Hoicowitz and Eugene Cobuzzi as executive vice presidents.
