Depending on the field of research it is quite common to publish only in open access journals [1]. At my university, we are actually only allowed to publish in peer-reviewed OA journals. Most of them provide a paid subscription for the print version while the online version is free and open to everyone. However, I got the (personal) impression, that this is only well established in fundamental research (which typically comes with few economic interest). As soon as the research is not paid by the state but by private companies (such as in medicine, robotics or any other "applied sciences"), scientists have a hard time to choose a OA journal (i.e. either it does not exist or you are not allowed to publish there). Changing this scheme is of course quite difficult, since too many commercial parties still benefit from it (which likely can only be change by law)...
