InnoVision Health Media, Inc. is an Eagan, Minnesota-based publisher of six online medical journals. The journals are supported by advertising and subscription fees, but they do have some open-access content. The journals appear to target health professionals and health care consumers.
I think that using the green open-access publishing model is better for authors and readers than publishing in a predatory or questionable open-access journal. Green open-access refers to publishing in a non-open-access journal and then uploading a postprint of the article to an institutional or disciplinary repository.
Virtually all the publishers on my list of predatory publishers maintain a website for the publisher with links to, among other things, their predatory journals.
