The World Without Ads

Most of us see sales pitches everywhere. One online community doesn’t.

Anyone who works in the $200 billion digital advertising industry should be scared of people like Mark Drobnak, because the ad blocker he uses is way more powerful than yours. The college freshman says it feels as though everyone at Rochester Institute of Technology, from his roommate to his professors, has installed some way to ward off online ads. But Drobnak is one of the die-hards who goes further, working with a handful of comrades to build what they call “a black hole for advertisements.” His parents say the one he built them works great.

Pi-hole (as in “shut your …”) is a free, open source software package designed to run on a Raspberry Pi, a basic computer that’s popular with DIYers, fits in the palm of your hand, and retails for about $35. Most ad blockers have to be installed on individual devices and work only in web browsers, but Pi-hole blocks ads across an entire network, including in most apps. (Two big exceptions, both for technical reasons, are YouTube and Hulu.) It can’t block ads inside Facebook, but it can stop Facebook from following you around the web. It’ll let you play Bejeweled without seeing ads between games, watch Mr. Robot ad-free in the USA app, stream NPR with silence in place of the sponsor messages, and avoid the banner ads that have become common on internet-connected TVs. If friends come over and connect to your Wi-Fi, it’ll block ads for them, too.
