"Marketplace" aired a story today that looked at how Google ads were used to good effect by the Scott Brown Senate campaign in Massachusetts. They're cheap, can be targeted to desired readers and showed up when voters googled Martha Coakley, Brown's opponent. "People think Google is a search engine," says Rob Willington, Brown's online strategist. "That's just one part of it. It's the new TV."

Also on the radio: On PRI's The World yesterday, L.A. Times correspondent Borzou Daragahi had a good piece from Shiraz, Iran on a music teacher who is allowed under Islamic law to teach women because he's blind. It ran last December in the Times.
