Facebook has grown tremendously since its founding, now with over 800 million users uploading photos and videos each month. However, it has faced significant privacy and business model issues. Facebook's initial Beacon program that shared user purchase information without consent caused a backlash. While the site provides valuable user data for advertisers, skepticism remains that Facebook can convert high traffic into sustainable revenue streams given user hostility over privacy and the immersive user experience making ads less effective. Facebook continues working to strengthen its privacy policies and identify business opportunities like e-commerce to profit from its massive user base.
