SAN FRANCISCO -- Nearly a year after its tumultuous split, General Motors Co. has updated its relationship status with Facebook Inc.
The Detroit auto maker said Tuesday it has begun advertising again on the giant social network. It said it's testing mobile ads for its subcompact Chevy Sonic.
GM did not say how much it was spending on the ads.
"Chevrolet is testing a number of mobile advertising solutions, including Facebook, as part of its 'Find New Roads' campaign," Chevrolet marketing vice president Chris Perry said in an emailed statement. "Today, Chevrolet is launching an industry-first ‘mobile-only’ pilot campaign for the Chevrolet Sonic that utilizes newly available targeting and measurement capabilities on Facebook."
Three days before Facebook's hotly anticipated initial public stock offering in May 2012, GM set off a firestorm of negative publicity for Facebook by announcing it would stop advertising on the social network because it said the paid ads had little effect on people's decision to buy a car.
The pullout of one of the nation's largest advertisers raised troubling questions about the effectiveness of ads on Facebook just as Facebook was trying to convince investors it was worth its $100-billion valuation.
