-  <hr>
   <p>{{aac-paragraph1[Acceptable Ads Committee Paragraph 1] In <fix>2017</fix>, <fix>eyeo GmbH</fix> handed over control of the Acceptable Ads initiative to an independent committee made up of eleven stakeholders who represent three distinct coalitions: User Advocates Coalition (digital rights organization, ad-block user), For Profit Coalition (advertiser, advertising agency, ad-tech company, publisher / content creator) and the Expert Coalition (user agent, creative agent, researcher / academia). This committee, aptly called the Acceptable Ads Committee, has full control over the Acceptable Ads initiative, including what’s deemed acceptable by defining the Acceptable Ads criteria. }}</p>
   <p>{{aac-paragraph2[Acceptable Ads Committee Paragraph 2] The committee's goal is simple: create new and exceptional ad standards that improve the user experience for ad-blocking users while, just as importantly, delivering real value to content publishers and online advertisers. }}</p>
