There's still plenty of alternative and underground animation and comics titles. Underground comics and animation is far from selling out and is produced by underground engineers who usually go by funky aliases on the internet. A lot of it's on the web.
Indie comics are: Webcomics on various webcomics and webmanga sites like Smack Jeeves, and DeviantART.
Underground animation is homemade bootleg and pirated anime websites (YouTube, Veoh), and DIY DVDs people like me make, and do share with friends and family, but don't really sell for the most part. Some people sell them, but many don't.
There's also online streaming Anime Openings and AMVs/MADs (anime music videos).
Good stuff, good stuff. Don't be hatin'. Hip-Hop kind of took off in a similar way.
