formatpixel has been built by electrolyte / Designer Boy.
Code pushing began in late 2005 to create an editing tool in flash with the aim of building an online editor to help the production of a paper-based magazine. The need was to help the editor and designers collaborate through the Internet on the layout of each issue. Over the months it developed and through various version of the editor it soon became apparent that so much more could be done with the system.
In early 2006 formatpixel was quietly launched and users were invited to try the system. Development of more features began on the core system and the community aspects of the site were built upon. It's main aim was then established which was to help illustrators, photographers, designers, artists and creatives to get their work online and viewable to the masses. To help explain the concept the term 'WTP' [Web Top Publishing] was used instead of 'DTP'[Desk Top Publishing] to illustrate the shift from the desktop to the web.
An overhaul of the core system was carried out late 2006 and a full public launch followed. Feb 2007 saw it featured on TechCrunch and the word was spread.
