Believe it or not, but email turned 40 last month. No one can question that email has transformed the way business is conducted. According to Radicati group, the average worker processes more than a hundred daily emails, and business email accounts make up only about a quarter of the total of more than 3 billion. Sometime in the next few years, Radicati predicts that the number of IM accounts will exceed email for the first time.

Electronic mail predates the inception of the Internet, and was in fact a crucial tool in creating it, but the history of modern, global Internet email services reaches back to the early ARPANET. Standards for encoding email messages were proposed as early as 1973. Conversion from ARPANET to the Internet in the early 1980s produced the core of the current services. An email sent in the early 1970s looks quite similar to a basic text message sent on the Internet today.

Email: officially over the hill.
