Although commercials have appeared on apps for a long time, if the videos are turned on automatically it will be a huge difference. Previously, users could ignore these videos indifferently, but now if the videos are run automatically, they will have more opportunities to reach the user's eyes, especially when more and more people are coming. Use social networks with mobile devices.
Facebook does not specify what 'eligible' movies to run automatically but perhaps the company will prioritize the most relevant clips to the installed user applications or software. For example, Facebook has announced it will strengthen its advertising focus for Amazon Fire devices.
The company broadcasts promotional footage widely in the New Feed section since March, but the Instagram app did this even a few months earlier.
