Trying not to sound too much like a sales pitch - but i stumbled on something really cool if you run you own web site. You probably run ad sense to make some cash right? This advertising network is like ad sense but instead of text ads, its audio ads the service hasn't launched yet - the ads will start playing on February the first 2008. The main advantages are these - doesn't take up any ad space - short 5 second audio ad - you get paid for every page view - put it on as many or as few sites as you like - paypal payouts - only $25 minimum payout Take a look at it it really sounds legit - and they claim to have partnered with one of the big 5 search engines.
