The 20th century was witness to the birth of what is arguably the most popular device in the history of mankind: the television. TV is a communications technology that has revolutionised the delivery of information, entertainment and artistic expression to the masses. More recently, we have all witnessed (and participated in) the birth of the Internet, a technology whose potential makes TV pale into insignificance in comparison (although, it seems, TV isn't leaving us anytime soon). These are fast-paced and momentous times we live in. I thought now would be a good opportunity to take a journey back through the ages, and to explore the forms of (and devices for) media and communication throughout human history.
