Sixty Seven Kilohertz developed a system that interjects updatable ads between the songs downloaded on a mobile device. "A user can download tracks for free and save them on a portable device such as a cell phone with MP3 player," said SixtySeven Kilohertz President Marc Cohen. "New ads are regularly transmitted to the device, saved, and played at non-predictable times between tracks of the free downloaded music. A user can listen to the same track many times and different ads each listening session."
