Humans have sought interconnectivity with each other since early days, and throughout history there have been specific technological developments that have each spurred human interaction significantly forward. As early as 3500BC, one of the earliest technological developments was written language. Allowing people to interact with one another more decisively regardless of physical distance, written language offered early humans an efficient and accurate system with which to facilitate trade, cultural expression and person communication. The desire to connect even inspired the development of written languages in separate parts of the world simultaneously. As technology advanced, faster and more cohesive ways of communicating were developed. Offering people the ability to speak in real time across virtually any distance, the telephone provided new levels of advanced communication and allowed global industrialization to leap forward with the rapid sharing of ideas. The telephone also paved the way for the medium we use most today — the Internet. From its humble beginnings as a US military project, the Internet now connects numerous aspects of everyday human life, and its capabilities encompass the sharing of voice, text, images and video. It facilitates virtually instant interactions in the social sphere, business, entertainment and commerce. It is also, like its predecessors, setting the stage for the next great technological development in human interconnectivity — the virtual world.
