Facebook is constantly evolving and expanding. Now reaching over 1.65 billion monthly active users per month, 1.5 billion of them via mobile device, the equivalent of more than 20,000 users is active on Facebook every second. Facebook is, by far, the biggest social network operating today, and a valuable website for marketers, whether they're promoting a product or service or conducting market research. In recent years, Facebook's been improving the experience it provides to its users so they can access a wider variety of content without ever leaving the site. For example, Facebook has put a significant amount of time and resource into developing its cross-platform mobile app to benefit Facebook members who access the network through smartphones and tablets. Video content is also being accessed on the go, with 75% of Facebook videos occurring on mobile devices, another key area of focus as the platform moves ahead. Facebook's also looking to provide businesses with new opportunities to communicate directly with their customers via Messenger, enabling them to have personal, real-time conversations. Additional advancements to Messenger include M, a virtual assistant through which users can book tickets, buy products and get recommendations without ever leaving the service.
