During these releases, it was common for web designers to display 'best viewed in Netscape' or 'best viewed in Internet Explorer' logos. These images often identified a specific browser version and were commonly linked to a source from which the stated browser could be downloaded. These logos generally recognized the divergence between the standards supported by the browsers and signified which browser was used for testing the pages. In response, supporters of the principle that web sites should be compliant with World Wide Web Consortium standards and hence viewable with any browser started the "Viewable With Any Browser" campaign, which employed its own logo similar to the partisan ones. Most mainstream web sites, however, specified one of Netscape or IE as their preferred browser while making some attempt to support minimal functionality on the other.
