This comes at a time when Mobile is quickly becoming the new normal for YouTube, and it’s starting to pay off: 40 percent of all of the service’s video views in the U.S. are now coming from mobile devices. Worldwide, mobile is now responsible for 25 percent of all of YouTube’s video views. This figure is bound to increase with these new product tweaks. There are other changes as well: the new YouTube logo, the “hamburger” menu, bigger thumbnails, new font, gray background.
