“In the Race to Buy Concert Tickets, Fans Keep Losing”
By Ellen Rosen
Published 6 October 2007 in the New York Times
Lisa Senauke, a Bruce Springsteen fan since 1973, tried to get tickets to his Oct. 26 concert in Oakland, Calif.
The tickets were to go on sale at 10 a.m. on Sept. 17, and starting at 9:58 a.m., she logged into her
Ticketmaster.com account, credit card in hand. But though she tried again and again for the next hour to buy
tickets, she was always told the same thing: nothing available.
Ms. Senauke’s frustration is not isolated. The coming concerts of…Miley Cyrus…sold out in minutes. And the
same thing happened with tickets to recent reunion tours by the Police and Van Halen.
While some fans just quietly give up, others have complained to government officials, particularly after they
found tickets to the same concerts available -- sometimes at many times the face value -- on secondary
sellers like Stubhub.com and TicketsNow minutes after the public sale began.

Because price ceilings limit a landlord’s revenue,
he/she will often cut costs in undesirable ways, such
as neglecting needed building maintenance.
