Channel 4 has owned the televisual rights to the event for the last four years and also owns the rights to the V Festival, while the BBC broadcasts Glastonbury. ITV also owns the rights to the Latitude festival.
Zai Bennett, ITV2 controller, said: "With bands including the Hoosiers, Nerd, The Zutons, and Kate Nash, the Isle of Wight Festival is a great event for ITV2. It promises to be a fantastic three days in June. I just hope the weather's as good as the acts."
The Isle of Wight Festival takes place this year between 13 and 15 June at Seaclose Park on the island. It was reincarnated seven years after an absence of several decades since its 1960s heyday
The original festival saw iconic acts including The Who, Bob Dylan and The Doors perform on the island. In 1970, the year it closed, guitar legend Jimi Hendrix played his penultimate gig before his death.
Festival organiser John Giddings, said: "After selling out all 50,000 of our tickets, it's great to be able to open the Isle of Wight Festival up to an even wider audience on ITV2 this summer. We've got some of the biggest names in music and to have live broadcasts across the three days is both a real tribute to the event's success as well as something I've always wanted."
Last month, BT announced a deal to become the main sponsor of the festival. The deal allows BT to advertise the tie-up as well as install its branding across the 250-acre site.
