Podcasting pioneer Adam Curry's PodShow company has acquired directory service, Podcast Alley.

Terms of the deal have not been disclosed, but it emerges after PodShow received $8.85 million venture capital funding from a trio of investors, all of which previously invested in Apple.

"PodShow's business model centres around promoting podcasts and finding sponsors for them," writes Silicon Beat.

The company also works with established media firms to help them make their own podcasts.
