Watch the short video on the right (or click www.weusecoins.com) under Video Bytes>> to see how it works and read the Introduction to Bitcoin to learn more. The full story of Bitcoin is well set out in the 'Wired' magazine article published in late 2011.
Bitcoin is a decentralized digital currency alternative to the existing and accepted government controlled printed and electronic bank money - ie. fiat money. Instead, the tasks of issuing new money (bitcoins) and verifying transactions is managed collectively by the p2p network.
Bitcoin can therefore be said to be a potentially disruptive technology to the status quo of, inter alia, bank, credit card and PayPal money transfers, as it does not require a high (overhead) cost banking network in which to operate. (Neither does Bitcoin require the payment of any/excessive bank bonuses to any members of its global network!)
(note: Bitcoins are impossible to inflate, like governments can do, by printing or creating additional electronic fiat money.)
Bitcoins are digital tokens accepted by individuals and companies as an alternative to money in exchange for the supply of goods and services.
Bitcoin enables instant payments from person to person to anyone anywhere in the world (using advanced p2p cryptographic* technology) on the internet with no central authority and without going through a bank or clearing house. Issuing Bitcoin money and managing Bitcoin transactions* are carried out collectively by the p2p network.
(*Bitcoin verifies transactions with state-of-the-art encryption that is used in military and government applications. Bitcoin is an extraordinary and important cryptographic innovation. It is the first system where a digital currency cannot be double spent. That means that your bitcoins can be duplicated perfectly any number of times, but they cannot be spent more than one transaction at a time between two people.)
Bitcoins are (almost) as anonymous as cash and impossible to chargeback. In fact, the use of Bitcoin to make online payments is like being able to spend 'cash' on the internet.
Use of the Bitcoin network is generally free, except for a tiny voluntary fee you can pay to speed up transaction processing. Find out more about how it works here and also here.
Bitcoin is also the name of the open source software which allows the universal use of this digital currency. Some background is in an interview in 2011 with two of the Bitcoin developers (bitcoin.org) in the two video clips below:

With Bitcoin's future growth and its potential universal adoption, many interesting and revolutionary possibilities begin to emerge - lower or zero inflation, instant and much lower cost (local and international) money transfers, freedom to spend at will without government interference to name but a few.
