These mobile websites are part of an extensive series of mobile-only websites for mobile phone users around the world. The service, Internet.org, is provided by Facebook. Users generally do not have an Internet account, but do have a mobile phone. Facebook provides the platform and underwrites the fees in arrangements with local mobile phone carriers. Organizations like Sesame Workshop, Intel, Nike, BabyCenter and many others provide educational and self-improvement content. The websites were built for small screens and minimal bandwidth.
