Adtruism raises money and awareness for charities through online advertising. If you have a Web site or blog you can raise money and awareness for any charity you like by embedding an iFrame. The iFrames display advertisements, the proceeds from which go directly to the charity of your choice. At present, all money goes to the charity chosen by the Webmaster, but the plan is to give everyone some say in where the money goes. To do this, a range of browser plugins and apps are being developed that will allow users to choose a combination of charities that they would consider their ideal donation ratio. When they visit a Website with one of this software's ads embedded, it can record their preferences and then revenue can be divided up accordingly.
