> Would 100 million be anywhere remotely close to enough for that? I think money is not the biggest hurdle. The problem with most ad networks is they copy google: most of the adsense alternatives for example are simply googles's ad partners that use google's ad exchanges. I think the ad space instead needs a "stripe for ads", a company that will quickly catch up with what publishers want, create solutions and push advertisers to use them. The alternative ideas include anonymous micropauyments.
