Podcasts are subscription audio recordings. You can get feeds of your favorite audio recordings and listen to them whenever you like. Odeo, founded by Evan Williams, was probably the #1 player in the fledgeling podcast market. Yahoo! just announced they are launching podcast search:

Hoping to tune into the latest craze in digital media, Yahoo Inc. is introducing tools for finding, organizing and rating “podcasts” — the audio programs designed to be played on Apple Inc.’s iPod and many other portable music players.

The Sunnyvale, Calif.-based company, which operates the world’s most visited Web site, plans to begin testing the new service Monday.

Search is rapidly evolving into a multimedia game. Check out Yahoo!’s podcast search at podcasts.yahoo.com
