Music and sports fans would have one less obstacle in buying tickets to popular events under a bill advancing through the California Legislature. Legislation by Democratic Assemblyman Richard Pan of Sacramento would prohibit the use of robotic ticket-buying software.

Supporters of AB329 say scalpers use the software to bombard online box offices and then resell tickets at higher prices. Several Assembly members supporting the bill urged additional steps to protect consumers seeking to buy or sell tickets. The Assembly approved the legislation, sending it to the Senate.
