Clear Channel Media and Entertainment and Relativity have renewed their cross-media marketing collaboration to promote Relativity film releases over the next 18 months.

The companies first teamed up in 2011 and have since collaborated on campaigns for “Limitless,” “Immortals,” “Act of Valor,” “Safe Haven” and “Free Birds.” “Immortals” is Relativity’s top domestic grosser at $83 million.

Relativity’s upcoming titles include action-thriller “3 Days to Kill” on Feb. 21, starring Kevin Costner;  the supernatural horror film “Oculus” on April 11; and the live-action family adventure “Earth to Echo” on July 2.

Terms of the new deal call for Relativity to provide exclusive content created by its filmmakers and talent for various Clear Channel platforms, including its iHeartRadio digital music service, national radio programs and top-rated local radio stations; select iHeartRadio branded events; and digital outdoor billboards in strategic locations around the country such as Times Square.

The programs will also include promotional support from radio personalities such as Ryan Seacrest, Elvis Duran, Dan Patrick and Steve Harvey; integrated film imaging; homepage website takeovers; national and local on-air commercials; and promotions for tickets, prizes and movie experiences.

“Relativity is consistently looking for innovative ways to connect our movies with audiences, and Clear Channel has the unique capability to connect to millions of people both locally and nationally,” said Relativity’s domestic marketing president Russell Schwartz.
