It's notable that the autoplayed ads The SEM Post noticed ran silently: back in February, Facebook confirmed that it would soon add sound to the videos it automatically plays in users' News Feeds. While that feature hasn't been fully rolled out, it hovers on the edge of every Facebook user's fear, haunting them with the possibility the internet will return to the nightmare mid-aughts when pages blared audio without permission. We'll wait to see whether Google cozies to the idea or leaves it alone.
