CBS Radio’s Live 105 is expanding an experimental format that blends the Internet and traditional broadcasting. As we noted back in October, Live 105’s ratings doubled on Sunday nights when listeners of the alternative rock station were invited to vote online for their favorite songs. The listeners voted on software created by a San Mateo startup, Jelli. As Live 105’s Menace explains in the video, listeners see a list of songs that will soon be played, and they can move the song up or down the list by clicking.
