Ryan Seacrest helped broker a deal between Relativity Media and Clear Channel (in partnership with his KIIS-FM radio show) to cross-promote major film releases over the next year.

Their first collaboration, Bradley Cooper's "Limitless," opened No.1 at the box office.

"For 'Limitless,' we feel the Clear Channel promotion significantly impacted our awareness and helped drive our successful opening weekend," said Relativity Media CEO Ryan Kavanaugh.

To promote the film, interviews with the stars aired on Clear Channel radio stations, stations played music hours that indicated 'you're listening to the Z100 limitless music hour sponsored by Limitless," and there were social media integration on station Facebook pages offering listeners the chance to win Limitless music; rich media overlays featuring Bradley Cooper walking onto home pages to promote the film; countdown clocks both on-air and on-line to provide high frequency reminders to the listeners and more.

Kavanaugh added, "As the consumer looks more and more to digital and interactive content, Clear Channel's cross-platform deal is a critical step in providing Relativity a direct link to its movie-going audience. Ryan Seacrest really envisioned this integrated partnership, and brought together all of the Clear Channel assets, people, and venues. Without his leadership, this deal would have never happened."

"Both Kavanaugh and Seacrest understood immediately the impact of leveraging Clear Channel Radio's portfolio of media assets and their vision was instrumental in developing this partnership," said Bob Pittman, Chairman of Media and Entertainment Platforms for Clear Channel Radio. "We look forward to developing even more creative campaigns going forward that will drive attendance for Relativity releases."

"Relativity Media is an ideal partner because of its interesting and compelling content offerings. I think we've only scratched the surface on the possibilities of blending between the studios and our digital and terrestrial platforms," said Seacrest, who was recently dubbed by The Hollywood Reporter as the most powerful man in reality TV.
