Meanwhile, several ads last night featured a whole lot of text. That’s somewhat surprising if you consider that a Super Bowl commercial break is a good time to, say, use the bathroom, get another beer, or refill the chip bowl. Text, unlike sound, requires your full attention. That seems like a pretty big mistake. But there’s one place where text-heavy ads make a whole lot of sense. That place where you don’t have the sound on—or don’t want to hear pesky ads. You know, like when you’re scrolling through Facebook on your phone, where videos—including ads—silently auto-play. What you can’t hear you might still read.
