listeners, we enable our listeners to create personalized stations and playlists, as well as search and play songs and albums on-demand. The Music Genome Project, our content programming algorithms and data collected from our listeners power our ability to predict listener music preferences, play music content suited to the tastes of each individual listener and introduce listeners to the music we think they will love. Founded by musicians, Pandora also empowers artists with valuable data and tools to help grow their audience and connect with their fans.

Pandora is available as an ad-supported radio service, a radio subscription service called Pandora Plus and an on-demand subscription service called Pandora Premium. The majority of our listener hours occur on mobile devices, with the majority of our revenue generated from advertising on our ad-supported radio service on these devices. With billions of data points that help us understand our users' preferences, we offer both local and national advertisers the opportunity to deliver targeted messages to our listeners using a combination of audio, display and video advertisements. We also generate increasing revenue from our subscription offerings.
