In the current "war" over hoarding access to scientific publications, for example, we have seen a scramble among traditional paper-publishers to grab a share (or try and hold-on to, and extend to the new media of the Internet, the traditional commercial share of business, they have always heretofore enjoyed), such as Wiley Intersciences, and we have seen the battle shaping-up among ostensibly "free" online services such as, Academia.edu , RG (and Google Scholar ?) to provide Open Access.
