The anniversary of the day when the first .com (or dot-com) name was registered should be remembered by everyone. That day was March 15, 1985.

It's the day that led to the birth of the dizzying digital age we now swim in and that's advanced science and technology to heights it never seemed capable of reaching. It's just a period and three letters but the extension ".com" was well and truly a game changer that changed our lives forever.

The first .com domain was Symbolics.com.

The now defunct company that owned this domain name, Symbolics, Inc., was a computer manufacturer in Cambridge, Massachusetts. Symbolics designed and made a line of Lisp machines or single-user computers optimized to run the Lisp programming language.

The Lisp Machine was the first commercially available "workstation." Symbolics also made significant advances in software technology, and offered one of the premier software development environments of the 1980s and 1990 such as Open Genera for Tru64 UNIX on the HP Alpha.

Such was the obscurity of the internet in 1985 that only five other firms registered domain names for the entire year. It would take two years for the first 100 names to be registered, said Verisign, the company that now manages the extension.

But between 1995 and 2000 (the era of the "dot-com bubble") registrations finally zoomed to over 20 million from just 9,005.

Today, new .com domains are registered at an average of one per second, said Verisign.

The .com boom gave birth to an incredible number of millionaires that profited from the Internet and new technologies that power today's world. Its economic impact has been massive to say the least and will even be more so in the coming decades.

The economic impact of the Internet will hit $4.2 trillion by 2016 compared to $2.3 trillion in 2010, according to the Boston Consulting Group.

Every one of the Fortune 500 companies and all of the world's fastest-growing corporations have a .com presence, said Verisign.
