Under the agreement, Yahoo Music will promote 150 of Clear Channel's concerts, and information about the music events will be made available throughout the Yahoo network.
In addition, information on ticket availability for concerts will be sent to Yahoo users. Alerts will be tailored based on geographic and demographic data, Clear Channel said.
The artists and groups that are part of the program include Coldplay, the Dave Matthews Band, Eminem, 50 Cent, James Taylor, John Mellencamp, John Fogerty, Ozzfest and Avril Lavigne, among others.
Clear Channel also said that in a recent survey, 70 percent of respondents reported that they get information about concerts online.
"The Internet has become a primary information source for concert fans, and that prompted us to shake up traditional concert marketing," Michael Rapino, CEO of Clear Channel Music Group, said in a statement.
