Roll20 is a web-hosted platform for tabletop games that allows groups of pen-and-paper gamers to play out campaigns entirely online. It provides text and video chats, player journals, turn tracking, dice rolling, background music, and a real-time shared graphical tabletop. Because Roll20 doesn't deal with game mechanics, it can be used with all kinds of tabletop games, including Dungeons and Dragons, Pathfinder, Shadowrun, FATE, and many others. Roll20 is designed for ease of use and requires no downloads or installations.
