lpress writes: At a recent conference, Comcast CEO Brian Roberts rationalized charging Netflix to deliver content by comparing Comcast to the Post Office, saying that Netflix pays to mail DVDs to its customers but now expects to be able to deliver the same content over the internet for free. He forgot to mention that the Post Office does not charge recipients for those DVDs. The underlying issue in this debate is who will invest in the Internet infrastructure that we badly need? Comcast has a disincentive to invest because, if things bog down, people will blame content providers like Netflix and the ISP will be able to charge the content provider for adequate service. If ISPs have insufficient incentive to invest in infrastructure, who will? Google? Telephone companies? Government (at all levels)? Premises owners?
