Google is shutting down its offline radio advertising program, Audio Ads and Adsense for Audio products. It is also making plans to sell Google Radio Automation.
About 40 employees working in Google's broadcast radio advertising sector can expect to lose their jobs. Advertisers will be able to use Google Audio Ads until May 31.
The move comes less than a month after Google's decision to shut down its print ad business, an effort which allowed advertisers to buy ads across hundreds of U.S. newspapers. The initiative was not as successful as the company had hoped, Google said at the time.
