“Facebook might be hosting upwards of 8 billion views per day on its platform, but a wide majority of that viewership is happening in silence.

As much as 85 percent of video views happen with the sound off, according to multiple publishers. Take, for instance, feel-good site LittleThings, which is averaging 150 million monthly views on Facebook so far this year. Eighty-five percent of its viewership is occurring without users turning the sound on.”
