Ticketmaster has agreed to buy ticket reseller Web site TicketsNow Inc. for a reported $265 million.

The move by West Hollywood-based Ticketmaster, a unit of IAC/InterActiveCorp that will be spun off into an independent company later this year, is a move to gain a stronger presence in the secondary ticket sales market.

Ticketmaster said Tuesday it planned to build a Web site that will allow customers to compare prices in the primary, premium and resale markets.

Financial terms were not disclosed, but a report in The Wall Street Journal said the deal was worth $265 million.

Ticketmaster is seeking new revenue after its top client, Beverly Hills-based concert promoter Live Nation Inc, said it will end its long-term ticketing agreement with Ticketmaster. Live Nation plans to start its own ticketing business in 2009.
