A discussion about corporate and business podcasting with tips and guidelines

There's a little snippet over on Andapr today about podvertsing. The quote is from a an eMarketer report and quotes podcast audiences being projected at:

• 10 million this year
• 25 million by 2008, and
• 50 million by 2010

That's all fine, but the next bit is about podcast advertising revenues:

• $80 million this year
• $300 million by 2010

Does that mean that an ad spot on a podcast is worth $8 this year and $6 in 2010? I'm in!
