Pandora is now serving ads in its stream. I haven’t heard them yet, even though I did listen to a good bit of music on Pandora today.
For what it’s worth, TechCrunch says the ads are “not that bad.” Audiophiles and anti-commercial activists may have other views.
If they choose, listeners can always sign up for the service’s $36/year premium membership and miss out on all the pitches.
