In the movies, during the first Act, there is often an inciting incident that sets the rest of the screenplay into motion.  It impacts the world in such a way that the course of history is changed forever.  If our screenplay was called, “History of the Web“, the inciting incident would probably be Sputnik.

The Russian satellite, Sputnik, was the first to be launched into space and set into orbit.

1957, The Soviet Union (USSR) successfully launched Sputnik 1958, President Eisenhower creates Advanced Research Projects Agency (ARPA) 1961, UCLA Professor publishes paper on packet switching

Likely, only baby boomers would have remembered this event but it scared the hell out of many Americans, especially those in politics.   The thing about Sputnik was two-fold;

1. It caught most people off-guard because the Soviets planned and executed Sputnik with extraordinary stealth, precision and secrecy.
2. It created enormous anxiety among many Americans causing them to fear that He who dominated space would dominate the world.

This knee-jerk reaction set into motion a series of events and a chain reaction that forever changed society and the world as we know it.  It set the Cold War into motion and a space race to the moon.  One unlikely offshoot of this historic event is the Internet.

1962, RAND studies command and control post nuclear attack 1964, Baran writes first paper, “On Distributed Communications Networks” 1965, MIT Larry Roberts conducts first computer network experiment 1966, The ARPA project begins. Larry Roberts is chief scientist. 1969, ARPAnet installed at UCLA and Stanford. First electronic message sent.

The basic premise of the Internet was that the United States needed a complex network of communication highways that would allow us to maintain a continuity of operations plan (COOP) in case one local hub (Washington, DC, for example) were to be taken out by a space-based weapon or nuclear ballistic missile.

The concept was not terribly different from the 1956 establishment of the Eisenhower National System of Interstate and Defense Highways, which would provide key ground transport routes for military supplies and troop deployments in case of an emergency or foreign invasion.

In 1991, Senator Al Gore was not far off when he referred to the future of the Internet as the Information Superhighway.  It was then that Gore helped to craft the High Performance Computing and Communication Act.

Remember the famous quote attributed to Al Gore, “I created the Internet“?  What Al Gore actually said to Wolf Blizter on CNN’s Late Edition in 1999 was, “During my service in the United States Congress, I took the initiative in creating the Internet.”  While he may not have actually invented the Internet, indeed, Al Gore was an Internet pioneer.

Sputnik occurred 7 years before I was born.  But, it wasn’t until the summer of 1969, when I was 5 years old that the Internet’s precursor, ARPAnet (Advanced Research Projects Agency network) was established and the first message was sent across the net.

For about the next 15 years, the Cold War heated up along with a nuclear arms race.  In fact, in 1982 I answered President Ronald Reagan’s call to action to defeat the “Evil Soviet Empire” and I joined the 82d Airborne Division. He offered a $20,000 bonus to Infantry enlistees that, at the time, was enough to finance my entire undergraduate degree.

In 1984, I was deployed to Honduras to train Contra rebels how to parachute from CH-47 (Chinook) helicopters and fight against the Cuban-backed Sandanistas.  Later, I discovered that this operation was part of  Ronald Reagan’s secret War and the Iran-Contra Affair.

But, I digress … back to the history of the Internet … after a brief pause.

1970, First packet radio network, ALOHAnet at U of H 1972, Tomlinson wrote first e-mail program, chooses @ symbol 1973, First ARPAnet connections to Europe (London & Norway) 1974, “Internet” is coined by Vint Cerf and Bob Kahn 1976, Metcalfe develops Ethernet to allow fast data transfer 1978, TCP split into TCP and IP 1980, Tim Berners-Lee of CERN writes precursor to HTML 1981, Microsoft creates DOS (disc operating system) 1983, Domain Name System (DNS) designed by Postel, Mockapetris & Partridge 1984, “Cyberspace” is coined by William Gibson 1985, Symbolic.com becomes the first registered domain name

In 1985, the year that I received an honorable discharge from the 82d Airborne Division, the Army sent me to a vocational college course to help integrate us Infantry folks back into society.  I had a choice of bar tending or computer programming.  I chose the programming class.

My first professional job out of college was at TRW, a defense contractor, on an Army project called the Army World Wide Military Command and Control Information System.  I was stationed at the East wing of the Pentagon in the Army Operations Center (AOC) beneath the parking lot.

It was during this period of time (1989-1992) that I was introduced to TCP/IP, the communications protocol that enabled interoperability between different computers and operating systems.  Allowing Macs, PCs and (soon to be extinct) mainframe computers (and ultimately, iPhones), to talk to each other was a crucial part of the system.

1986, 5,000 web sites across the Internet 1987, 10,000 web sites across the Internet 1989, 100,000 web sites across Internet 1990, Tim Berners-Lee and Geneva’s CERN implement HTML 1991, Al Gore crafts High Performance Computing and Communications Act 1992, CERN releases World Wide Web 1993, Marc Andreessen launched Mosaic web browser 1994, Yahoo! founded by David Filo and Jerry Yang of Standford 1995, Browser war begins (Mosaic, Netscape, Internet Explorer

A few years later, I worked at the Defense Information Systems Agency (DISA), a distant cousin to DARPA (Defense Advanced Research Projects Agency), and it was there that I first started using HTML and helped to create and maintain one of the agencies first world wide web sites.

In 1994, I remember buying a book called something like, “Directory of the World Wide Web.”  It was basically a printed Yellow Pages of Internet sites.  Of course, within about 4 months the book was obsolete because the number of websites was growing at a rate of about 25,000/month.  Obviously, there was a growing need for a dynamic database of websites.  That was the year that Yahoo! came out.

By 1995, that I knew that the Internet was going to be something huge.  So, I began registering hundreds of domain names, including photographer.com.  It was also amazing to see traditional photography go digital and the morphing of digital imaging and web design.

1996, AOL provides open access to the internet 1997, Business.com sells for $150,000 1998, Google is founded by Larry Page and Sergey Brin 1999, AOL Buys Netscape ($10 billion) declares browser war officially over 2000, Dot-com bubble bursts, AOL merges with Time-Warner 2001, Al-Qaeda uses Internet to coordinate 9/11 terrorist attacks 2002, Pornographer hacks Al-Qaeda site, Friendster launches 2003, Wordpress and MySpace launch

As a semi-professional photographer with a BS in Business, MS in Information Systems and insight into the world wide web; the stars seemed to be uniquely aligned.  Within a couple months of launching photographer.com, I was getting huge contracts from very wealthy people and flying all over the world to shoot special events.  It didn’t take long to realize that I needed to quit my $50,000/year government job and go private.  So, in 1998, I separated from the government and became obsessed with Internet marketing and web development.

Back then, it was easy to get found on Yahoo and easy to get listed in DMOZ – The Open Directory Project.  But, as time went by, it became more and more difficult to stay on top.  By 1999, Google was proving to be a very effective search engine and by 2000, my obsession began to shift from just web design to search engine optimization.

I was also amazed at the social activity that was happening online.  I still had an account on AOL and people out of the blue would instant message me.  Looking back, a significant number of my relationships – both professional and personal – were formed online.  I didn’t realize it at the time, but this was social media in the making … and it was amazing!

By then, probably 85-90% of my business came to me through the web.  The foundation of traditional advertising and marketing was about to discover the phrase, “smackdown!”

I moved from Washington, DC to California because, after all, that was  Internet mecca.  It was amazing to be around a bunch of brilliant, like-minded people who share a similar vision and obsession with regard to the web.

During this time, I saw e-commerce firms sprout up over night and sell a quarter million dollars worth of merchandise in a month.  I learned all about web analytics, blogging, cascading style sheets (CSS), content management systems, e-commerce platforms, open source software, social media, project management, affiliate marketing, outsourcing and, most importantly, search engine optimization (SEO).  I saw companies like AOL burst onto the scene and then fizzle out like meteors and comets streaking across the sky.

By now, it is impossible to keep Internet milestones down to one line, thought or accomplishment per year

2004, Faceook launches, Google IPO @ $85/share 2004, Osama Bin Laden post message directly to the web 2004, Howard Dean’s successful Meetup.com changes political campaigning 2005, YouTube launches to massive viral success 2005, Steve Case resigns from AOL as AOL continues downward spiral 2005, Google launches Google Maps and Google Analytics 2006, 100,000,000 world wide web sites 2006, Google acquires YouTube for $1.65 billion 2006, Twitter is founded by Willams, Dorsey and Biz Stone 2007, Apple launches and sells 5,000,000 iPhones 2007, Apple surpasses one billion iTunes downloads 2007, Marc Andreessen launches Ning Do it Yourself (DIY) social networking platform 2007, Netflix delivers movies over the web 2008, Google launches Chrome, Android, G1 Phone 2008, 1.5 billion people online 2008, Obama leads historic online campaign to win Presidency 2009, Obama uses YouTube to deliver message to Iran 2009, Protestors in Iran use Twitter to organize rallies 2009, United States government asks Twitter to delay maintenance 2009, Bing bursts onto the scene and overtakes Yahoo! to be #2 2009, Real-time search is born

As the web continues to evolve, I am thrilled to have been an active part of its growth from an early adopter to crossing the chasm into mainstream society.

Len Kleinrock – one of the Founding Fathers of the Internet

History of Internet Users Across Social Media

Social media statistics by number of users, members, subscribers, unique visits
