MTV and VH1 will broadcast eight hours of the Live 8 concerts on July 2, the networks have revealed.
The performances, featuring artists such as U2, Coldplay, Madonna, Dave and Jay-Z among many others, are being held in eight cities to raise awareness of poverty in Africa.
The broadcast is a repeat performance for MTV, which showed the Live Aid concerts two decades ago.
It is also expected that the concerts will be shown live on the internet.
MTV and VH1 will be on the air with the same feed from 11am to 7pm that day, switching back and forth from different sites and also presenting packaged reports, like a look back at Live Aid.
