YouTube, the biggest video site on the planet, deals a lot in big numbers, so its latest milestone is no exception.
Thursday, the Google-owned video service said it has automatically captioned 1 billion videos.
Captions, subtitles on clips that transcribe dialogue and note other audio clues occurring on screen, are a technology that makes videos more accessible for those with hearing impairments, which the World Health Organization estimates is more than 300 million people worldwide.
But as silent autoplaying videos become a norm alongside the rise of mobile viewing, the tool has widened in use to anyone watching a clip in a quiet place where sudden piercing loudness might be frowned upon (i.e. church, class lectures, your next all-hands work meeting -- not that I know from personal experience).
Google first launched video captions back in 2006 and automated them three years later. In addition to the 1 billion milestone, the company said people watch video with automatic captions more than 15 million times per day.
