From an August 18 New York Times article:

Dr. Schlessinger took a different tack this time, apologizing on her blog and on the air the next day. Still, a day after her apology, the liberal watchdog group Media Matters for America posted audio of her original comments online and later called for advertisers to boycott the program.

The movement gained traction, as General Motors' OnStar and Motel 6 pulled their sponsorships of the program, according to Corinne Baldassano, senior vice president of Dr. Schlessinger's production company.

Ari Rabin-Havt, a vice president at Media Matters, said this incident “should serve as a lesson to radio hosts that their words matter.”

“They can and should be held accountable for what they say on the airwaves,” Mr. Rabin-Havt said.
