"Incorporating the radio into the native environment of the car has remained a key focus for the company since announcing its first automotive brand partnership with Ford (F) in 2010. In January, Pandora created a new source of revenue by rolling out in-car advertising solutions and said the service is available on nine out of the ten best-selling passenger vehicles. Advertisers can reach car-bound audiences through 15-second and 30-second audio spots that will run across the 130 vehicle models that include a native Pandora integration along with more than 270 aftermarket automotive devices that feature the personalized radio service. Major brands such as BP, Ford, State Farm, and Taco Bell have signed up for the campaign. The company said more than 4 million users have activated Pandora through a native integration across the 23 major auto brands and eight aftermarket manufacturers on the company’s partner roster, representing an increase of 244% year-over-year.
