Eastlan continues to expand its radio audience measurement footprint, adding Seattle and Oklahoma City as the latest markets to receive its monthly ratings service.

The first Eastlan reports for both markets will be released on Tuesday, June 30, alongside inaugural monthly books for Atlanta, Chicago, Cincinnati, Dallas and Houston. The additions bring Eastlan's expansion to nine of the nation's 50 largest radio markets over the past 12 months.

The company said the growth comes as the radio industry increasingly shifts toward impressions-based advertising sales, creating greater demand for affordable third-party audience measurement that includes every station in a market.

Unlike measurement services that exclude some stations, Eastlan said its ratings encompass all stations, providing buyers and sellers with a more complete view of radio listening. The company said users can evaluate both total campaign impressions over a six-week flight and average quarter-hour audience estimates for every station in a market.

"Buyers remind us each day that radio still needs third-party data that underscores its importance," said Eastlan President Mike Gould. "The key difference with Eastlan is it allows all users to see the strength of all radio stations in each market, whether that is total impressions of a six-week flight or the AQH rating for every station in town."

Gould added that the company is hearing increasing frustration from radio buyers who say current measurement services that arbitrarily exclude stations make it more difficult to confidently evaluate and purchase radio advertising.
