Some ads are more annoying than others are and that has led many web users to run ad blockers that stop them from having to look at ads. Apple has already added an adblocking API to iOS and now Samsung is following with a similar ad blocking service. Samsung has teamed with Adblock Fast and is rolling out an ad blocker to users via an OTA update.
Adblock Fast is an open source ad blocker designed to use the Samsung internet ad blocking API. Version 4.0 of the service is rolling out as of today but still isn't live for everyone at this time. Samsung internet 4.0 is compatible with Android 5.0 only right now, but support for Android 4.x is coming soon.
This is the first extension that uses Samsung's adblocking API integrated into Samsung's web browser, but it certainly won't be the last extension. Adblocking is nothing new, other extensions and browsers have allowed users to block ads for a long time.
Ad blockers are useful to kill ads that might be nefarious. With Samsung and Apple both baking ad blocking into their mobile devices, legitimate publishers who use ads to support their networks and stories are concerned about paying bills in a world where all ads are viewed as a bad thing.
