Blackspot Radio goes beyond being non-corporate: they are explicitly anti-corporate.

What would a Blackspot Radio station look like? Perhaps very similar to RadioParadise is an entirely listener supported, anti-corporate radio station that has about $1,000,000 in annual revenues and provides music to 15,000 listeners at any given time. And best of all, they actually pick their music using their brains, not a computer.

Here is in their own words:

Each hour of music is carefully blended together to flow smoothly between different musical styles & genres - just like real DJs used to do on FM. We don't use the computer-generated playlists or "carefully researched music libraries" that have sucked the soul out of FM radio - and we never just throw songs together at random the way many web stations do.

Our plan is simple: we create the best station we possibly can, refrain from contaminating it with advertising, and then ask you to pay us what you think it's worth. So far it seems to be working out nicely. We're not likely to get rich this way, but that's not our goal.

Here at RP we're not just non-commercial. We're anti-commercial. We feel that quality radio programming and advertising just cannot co-exist. We also choose to refrain from forcibly extracting money from you by charging subscription fees. We leave it up to you to decide what our service is worth to you.
