One of the major things users wanted to do was download content, and expand the functionality of their devices. So I helped design one of the first app stores anywhere, maybe the first mobile centric app store, and certainly the first functional one in the U.S. It started selling ringtones, then moved into applications (for featurephones), subscription services, and other products. Of course we designed it to handle all this from the start, so expansion was easy when the content arrived.
The popup above, and the entire page below, focus on music. Another key function (launched first as an independent product due to partnerships with a vendor) was to sell and manage complete MP3 tracks, which went on the Samsung Uproar M-100, the first MP3 phone anywhere (yes, even Japan).
It was... not a success. And the vendor solution was clunky, but we did it and whether the designs I used were emulated or we all simply came up with the right answer independently, all the music, ringtone and app stores today look an awful lot like this still in many ways.
