HTML5 is accepted by Defy Media Network and will work correctly within HTML5 enabled browsers and environments. If users have the latest versions of Chrome, Safari, Internet Explorer, or Firefox, their browser is already capable of handling most code written in HTML5. If a user’s browser is not updated, backup images will display instead of the HTML5 creative. HTML5 creative should follow the same advertising specifications as other Standard and Rich Media creative developed for each site. As with other rich media, HTML5 will require testing and approval 10 business days prior to launch.
