George Brock discusses how the concept of "fast food news" is based on outdated assumptions about how news is consumed on mobile devices. While early mobile news focused on small snippets of information for small screens, mobile devices like tablets now allow for in-depth articles through larger screens. Brock argues the larger issue is the speed of the news cycle, not brevity of content. Despite technological changes, the core tasks of journalism - verification, sense-making, witness, and investigation - remain important. Journalism must find a business model that supports these tasks in a mobile, connected world.
