If you're not paying for YouTube Red, you're likely used to the many different types of advertising the video service features. But next year, one of the more irritating formats will be going away. YouTube says that it'll stop supporting "unskippable" 30-second pre-video advertisements in favor of shorter formats. A YouTube spokesperson confirmed the change with this statement: "We're committed to providing a better ads experience for users online. As part of that, we've decided to stop supporting 30-second unskippable ads as of 2018 and focus instead on formats that work well for both users and advertisers."
