Along with becoming more user friendly, Twitter's next big change is focusing on videos and ads. Now, instead of being limited to the mobile app, users can upload video from their desktop computers straight to the website. In turn, Twitter is cranking up its advertising initiative 'Amplify' for more YouTube-like pre-roll ads on premium videos from partners like the ones shown above. At a conference held in New York today, Twitter also announced that it will add a GIF generator and allow Periscope to play within the timeline. So if you're wondering why you're seeing a whole lot of moving content in your feed, it's because publishers are now able to easily monetize their work.
