1. First Image.The first image in web history was... four women, all of whom now probably regret being part of the first image in web history.
A programmer named Silvano de Gennaro worked for CERN (the European Organization for Nuclear Research, located in Geneva, Switzerland... aka the birthplace of the World Wide Web).
In 1992, the non-ManBearPig-focused founder of the World Wide Web, Tim Berners-Lee, had just built this new information system called the World Wide Web, and created the first website,
http://info.cern.ch.
Berners-Lee asked Gennaro to scan some photos from a CERN party and post them on that page. Gennaro didn't really get what he was talking about but scanned in the photos, FTPed them to the server and linked them to a page. The picture of the four women, complete with their early '90s "Don't Tell Mom The Babysitter's Dead" fashion sense, was the first one ever viewed in a web browser.
And if the cougar in the silver sparkles had just leaned a tiny bit more, this could've simultaneously been the first nude photo on the Web.
2. First E-mail. E-mail as we know it was created by a programmer named Ray Tomlinson, in 1971. People had been sending electronic messages before... but only to people on the same computer. Tomlinson created the e-mail structure that's still used today --
guy@site.stuff. (Apologies, by the way, to the real
guy@site.stuff, whose e-mail I just exposed to hundreds of hungry spambots. Hope you like hearing about the magical powers of Acai berries!)
By bringing the "@" symbol in, it separated the e-mail user from his machine, and, therefore, he could send his electronic message to anyone on any machine. (I use the male pronouns here not because I'm sexist, but because no woman in the history of women would've been dorky enough to be an e-mail pioneer at this stage. Not even you, Marie Curie.)
So what did Tomlinson write in his first e-mail? He... doesn't remember. Best he can recall, quote, "the test messages were entirely forgettable... most likely the first message was 'QWERTYUIOP' or something similar."
The first real e-mail he sent was a message to his co-workers... explaining how to use e-mail over the network.
3. First Spam E-mail.With the first real e-mail out of the way, the door was open for the first spam e-mail. Although, based on best estimates, it took a solid seven years before someone realized that strangers on the Internet were the best target market for unsolicited penile enlargement help.
The first spam e-mail was sent out in 1978 by Gary Thuerk, a marketing rep for DEC.

The Digital logo.
(That's the Digital Equipment Corporation. You'd probably recognize their logo. They ended up going belly up in 1998. And for a computer company to die in 1998, you know they did NOT have their [LIFTED] together. In 1998, you could slap the letter "e" before any word, call yourself a company and make a billion going public the next morning.)
Gary sent this e-mail, unsolicited, to every available west coast e-mail address he could get his hands on:
DIGITAL WILL BE GIVING A PRODUCT PRESENTATION OF THE NEWEST MEMBERS OF THE DECSYSTEM-20 FAMILY; THE DECSYSTEM-2020, 2020T, 2060, AND 2060T.

The reaction was... not good. In fact, this spam message got even more hate than spam today. Because the modems in 1978 were slow, downloading a long e-mail like this (long because it had so many people's e-mails listed) could choke people's computers. It even, apparently, shut down a system at the University of Utah, and drew a strong complaint from the Defense Communications Agency.
4. The first banner ad ever.The people behind "Wired" magazine decided to start the first commercial web magazine, called "Hotwired", in October of 1994. And they put the word out: Buy advertising in our new, online-only magazine.
AT&T was the first company that did. And instead of taking the straightforward approach, they used an online advertising strategy that would launch a billion "punch the monkeys"... a mystery ad trying to goad readers into clicking.
But who knows -- in 1994, that might have worked.
5. First Item Sold on eBay.Pierre Omidyar started eBay in September of 1995. And Omidyar sold the first item on eBay... a broken laser pointer that went for $14.
And, quite frankly, I can't think of a first item more emblematic of the eBay experience than a broken laser pointer.
6. First Tweet.Biz Stone, one of the co-founders of Twitter, posted the first Tweet ever... just 11 minutes before the other co-founder, Evan Williams. On March 21st, 2006, at 12:51 PM, Stone Twittered: "just setting up my twttr".
And, quite frankly, I can't think of a first Tweet more emblematic of the Twitter experience than Stone's punctuation-, capitalization- and spell check-free offering.
7. First Search Engine.The first search engine was called Archie, and was created in 1990 by Alan Emtage, a student at McGill University in Montreal, Quebec, Canada. I didn't look up what has since happened to Alan, but I assume at some point around 2004 he hung himself by his neck in his [LIFTED] closet for not pushing himself just a slight bit harder and coming up with Google.
Anyway, you can still use a version of Archie here... but, for whatever reason, it only lets you search worldwide anonymous FTPs or Polish websites. Only searching Polish sites? Such a fall from grace for the first-ever search engine. Just another reason why Alan's decomposing body was probably found by the police with things like "Gmail" and "Adsense" and "I'm feeling lucky" carved into his flesh.
8. First Domain Name.The first domain name ever was Symbolics.com, registered on March 15th, 1985, by a computer manufacturing company called Symbolics... that no longer exists.
Their fatal flaw was staking their entire company on a programming language called Lisp. To draw a metaphor, that's like starting a restaurant and declaring that the main ingredient in everything you cook is going to be pickled herring. That's like founding a porn studio but only releasing your movies as 8mm filmstrips. That's like getting an NFL expansion team and building it around Tim Couch.
9. First YouTube video.The first YouTube video features Jawed Karim... who's like the Brian Dunkleman of YouTube founders... standing at a zoo, talking about an elephant. It was posted on April 23rd, 2005.
Like most YouTube videos, it's so boring that it manages to make 19 seconds feel like a solid two minutes. Karim is the far more interesting story -- I love this article in "USA Today" where Karim casually mentions that, even though he's not considered one of the two guys behind YouTube, it was all his grand idea. But he let the other guys have it because "my only interest was in helping the company get off the ground." Of course. And Vin Diesel only came back to be in "Fast and Furious" because he really connected with the script.
10. First Porn Website.It's hard to prove definitively, but it's believed that the first porn site was sex.com. It was registered in 1994 by a guy named Gary Kremen.
Yes, that rhymes with semen. However... Gary did not have pornographic intentions with sex.com. At least that's what he says today.
A guy named Stephen M. Cohen, which rhymes with bone (and "moan"... and "sex, phone" and "she moves her body like a cyclone"), DID see the pornographic potential of the domain. So he contacted Network Solutions, which administrated all domain names back then, and fraudulently had the ownership of sex.com transferred to his name using a series of fake faxes and forged documents.
He quickly turned it into a thriving, profitable and dirty porn site.
Kremen was furious, and sued Cohen. After a long court battle, Kremen won a $65 million judgment and got the rights to sex.com back. Before he could get the money, though, Cohen fled to Mexico and moved his money to an offshore account. He was tracked down in 2005 and turned over to U.S. authorities.
Kremen sold sex.com for $12 million. In between fighting for sex.com, he had the time to found match.com. Which, I'd guess, has led to exponentially more actual sex than sex.com.
11. First Member of Friendster.Founder Jonathan Abrams, profile #101 was the first member of Friendster. And may also be its last one left.
