Ad blocking

Ad blocking or ad filtering is removing or altering advertising content in a webpage. Advertising can exist in a variety of forms including pictures, animations, embedded audio and video, text, or pop-up windows and can employ autoplay of audio and video. All browsers offer some solution to the problem, either by targeting technologies (Adobe Flash/Shockwave, Windows Media Audio files, etc.) that are used to deliver ads, targeting URLs that are the source of ads, or targeting behaviours characteristic of ads (such as the use of HTML5 autoplay of both audio and video).
