Apple's Latest Acquisition Has Officially Shut Down Its Radio Service

Just a day after Apple $4, the personalized radio and podcast application has officially shut down. Swell's shuttering, $4, was "part of the deal."

When you try to play a radio station or podcast, you'll receive the following message:

Thank you so much for supporting Swell. We want to inform you that Swell is no longer available. We've been inspired by the opportunity to create a quality product and are so grateful for your support. For more information, please visit the Swell website at www.swell.am.

Swell previously raised $7.2 million from investors including Google Ventures, DFJ, and InterWest Partners.

$4 that Apple paid $30 million for Swell.

The company was previously working on a version of Swell for Android, but that's obviously not going to happen.

$4 and how it will fit into Apple's ecosystem.
