Olive Media has announced it is now representing the mobile advertising inventory for Jumpstart Automotive Group’s sites.

The announcement expands Olive Media’s partnership with the Hearst magazine brands, which include Car and Driver, Road & Track, Car Soup and Car Buzz into its mobile web and app opportunities as well as tablet advertising options after the company has been working with the titles on desktop for the past three years.

Titles in the group reach a predominantly male audience of auto enthusiasts and car buyers in the 25-to-34 age range, according to an Olive Media representative. Approximately 30% of all Jumpstart site traffic is accessed via mobile, with tablets representing about 36% of mobile traffic.
