Podcasting network Wizzard Media announced on Wednesday that it has surpassed 200 podcast-related iPhone Apps in the iPhone App Store, bringing the total number of paid Apps to 260 for the iPhone and iPod Touch platform.

The company also announced first quarter unique monthly podcast audience numbers of 18.5 million, up slightly over the first quarter of 2009. When adjusted to account for the shift of the Company’s free podcast hosting services to an all paid platform in mid 2009, Wizzard estimates unique monthly audience for its podcast network up approximately 23% “on a pro forma basis.”

“Our revolutionary podcast App allows podcasters to monetize their already-established, iTunes-based podcast audience, said Chris Spencer, Wizzard Media CEO. [Our podcast App lets podcasters sell listeners] paid access to bonus content, the ability to charge for virtual goods and sell subscription packages for reoccurring revenues. This new product changes everything for our industry.”

Wizzard Media provides podcast publishers with distribution and monetization services to clients like Microsoft, National Geographic, Harvard Business Review, Usher, NPR and more than 13,000. Wizzard Media products measure clients’ podcast audience, deliver popular audio and video entertainment and enables podcasters to “monetize content” through advertising and App sales. According to its own calculations, in 2009, the Wizzard Media Network received over 1.4 billion podcast requests from approximately 50 million people worldwide through iPods, iPhones, iTunes, Zune and many other devices and destinations.
