+{{about-abp[Paragraph in "about" section] Adblock Plus is a tool that lets users block [ads](https://easylist.to/2011/07/11/the-definition-of-advert-and-link-exchange-policy.html). Since ads fuel a lot of the content we enjoy for free online, finding common ground seemed to make sense. We asked our users about this and they overwhelmingly agreed.}}
 
 {{abp-history[Paragraph in "about" section] So starting in 2011, in consultation with [our users](/blog/adblock-plus-user-survey-results-part-0), we decided to propose a compromise. Because we share a vision with the majority of our users that not all ads are equally annoying, the Acceptable Ads initiative was created. It allows advertisers and publishers who have agreed to make ads that abide by user-generated criteria to be whitelisted. Users can support this less extreme version of ad blocking by allowing the Acceptable Ads option to remain enabled. To browse completely ad-free, users can [disable the option](#optout).}}
 
 {{benefit[Text in "about" section] The Acceptable Ads initiative is beneficial because it encourages the ad industry to pursue less intrusive ad formats, thus having a positive impact on the Internet as a whole. It also provides us with a [viable source of revenue](/about#monetization), paid only by larger participants in the Acceptable Ads initiative, which we need in order to be able to administer and maintain the program and continue development of a free product.}}
 
 {{our-belive[Paragraph in "about" section] We believe that this initiative is a sustainable middle ground between the user's choice to use ad blockers and the continued need to support free online content with advertisements. In general, an Acceptable Ad is a non-animated ad, clearly labeled as such, that does not interrupt reading flow. It is important to note that these criteria try to reflect the ongoing discussions between our users, publishers, advertisers and us. As [previously announced](https://adblockplus.org/blog/campdavid-nyc), in 2017 eyeo / Adblock Plus transferred management of the Acceptable Ads initiative to an independent group of people, the [Acceptable Ads Committee](https://acceptableads.org/).}}
