Even the giants want a piece of the action when it comes to broadcasting online.  Just this week, Clear Channel opened up a new music site called “Erockster” a site aimed to people 13-34 with a mix of classic and indie rock, soul, dance and hip-hop. The site is designed to attract many – both traditional radio listeners and those who have chosen to abandon conventional radio. There is a social networking component as well as an option for on-demand and links to sites like i-tunes. As of today, the site was streaming from CC stations in LA, DC and Philly with more markets on the way. The site will have an air-presence on HD channels throughout the country.

Meanwhile, over the summer CBS is expected to launch “play.it” where listeners can choose music by their favorite artists and have a customized playlist made up of those artists and new artists who might match the genre.

More at the PG.
