If the early web tended to privilege text, today's web is deeply multimodal-full of image, sound, and video. The online photo-sharing site Flickr hosts billions of images, with roughly 1.83 million images uploaded daily in 2014; Instagram, launched in 2010, now surpasses 70 million photo uploads a day. An average of 300 hours of video is uploaded to YouTube every minute.
