In "The Wealth of Networks" Benkler two times mentions that newspapers don't rely on exclusive copyrights in their business models. Copying would delay the news too much and readers would not buy it. Online this does not hold anymore - articles can be copied in no time, but still 50 years of exclusive copyrights seems excessive to me.
There should be a Creative Commons license crafted specially for online news - with exclusive copyrights for a much shorter period, let's say 24 hours. This should be long enough to destroy the business of blatant copy-cats but short enough that it has value to those that really want to add something to the articles.
A business model that charges for real time news but opens the archives for commenting and weaving the articles into the public discourse seems a lot more compatible with the Internet economy than publishing current editions of newspapers and charging for the archives that some journals do.
