Yahoo is reporting:

A Boston-based company called Jingle Networks offers this free alternative to expensive 411 calls via your cell phone or land line. How and why do they do what they do for free? Just as radio and TV shows are supported by advertising, the directory assistance service is sponsored by companies advertising with the service. So, yes, that means you may hear a short, audio ad when requesting a phone number, but not every time.
