Nearly two years after AT&T pulled its advertising off YouTube after it discovered its spots were appearing next to “extremist content,” the company has announced it will again be placing ads on the platform.

It comes at a time when YouTube usage is growing, and according to Pivotal Research analyst Brian Wieser, the video platform is being described as an add-on to television buys. He estimates YouTube viewing by U.S. adults (18+) increased 25 percent in December and was up 29 percent for all of 2018. “YouTube now equates to 15 percent of total TV time. This is similar to the share of viewing the industry’s largest player (NBCU) has,” Wieser says in a new report.
