Pandora is the leader in internet radio in the United States, offering a personalized experience for each of our listeners. We have pioneered a new form of radio-one that uses intrinsic qualities of music to initially create stations and then adapts playlists in real-time based on the individual feedback of each listener. As of January 31, 2013, we had approximately 175 million registered users, which we define as the total number of accounts that have been created for our service at period end. As of January 31, 2013 approximately 140 million registered users have accessed Pandora through smartphones and tablets. For the fiscal year ended January 31, 2013, we streamed 14.01 billion hours of radio and as of January 31, 2013, we had 65.6 million active users during the prior 30 day period. According to a December 2012 report by Triton, we have more than a 70% share of internet radio
among the top 20 stations and networks in the United States. Since we launched our free, advertising-supported radio service in 2005 our listeners have created over 4.0 billion stations.
In June 2012, we entered into or activated agreements which allow Pandora to launch in New Zealand, Australia and the territories associated with the two countries. The arrangements with PPNZ Music Licensing Limited, which represents recording artists and record companies, and APRA/AMCOS, which represents songwriters, composers and publishers, have not had a material effect on our results of operations to date.
