History of the Internet
The internet was not born as a finished system. It was built across decades by researchers, engineers, operators, institutions, and communities who chose openness, interoperability, and shared stewardship before the world knew what the network would become.
History of the Internet is BTW Media's editorial archive of the people, protocols, institutions, and turning points that shaped the global network.

Protocols that became infrastructure
TCP/IP, DNS, routing, email, the Web, number resources, and standards processes made global interoperability possible.
Memory for the next generation
Interviews, profiles, and records preserve how the internet was imagined, governed, expanded, and defended.
This collection brings together interviews, profiles, source-backed reporting, and historical analysis about the builders and witnesses of the internet age.
This page follows how individual decisions, technical principles, public institutions, and regional communities became civilization-scale infrastructure.
For the people recorded here, this is a record of contribution. For readers, it is a map of how the internet became one of humanity's shared systems.

eBay Let Strangers Rate Strangers. Then It Had to Police the Raters.
Pierre Omidyar asked AuctionWeb users in February 1996 to praise good trading partners and make complaints in public. By eBay’s 1998 annual filing, the company had rules against self-praise and retaliatory ratings, a waiting period for new accounts and staff investigating misuse. A public reputation system needed its own referee.

AOL Paid $287 Million for ICQ. Mirabilis Had No Revenue.
In June 1998 AOL bought a chat habit before it bought a chat business. Mirabilis had millions of active trial users and no revenue; AOL pictured a desktop portal where that habit might finally pay.

Google Bought Deja's Usenet Years. Readers Initially Searched Months.
In February 2001 Google acquired Deja.com's archive back to 1995. The new Groups search launched with more than six months of posts. The older conversations had changed hands faster than they became searchable.

Google Bought Deja’s Usenet Archive. Search Opened With Only Months of It.
On 12 February 2001, Google said it had acquired Deja’s entire Usenet archive dating back to 1995. The new Google Groups beta could search more than six months of messages. An archive can change hands in a day; making its contents available to readers is a different job.

CyberCash Hid the Card Number. The Acquiring Bank Could Hand It Back.
CyberCash's 1996 protocol routed a customer's card details past the shop and into a payment server. The shop still had two ways to see the number. One depended on its bank; the other left a record of the request.

MapQuest Put Directions on Your Screen. Its Map Factory Could Run on Someone Else’s Server.
The familiar late-1990s MapQuest page was only one place where its routes appeared. In 1999, a business could show MapQuest maps on its own website, pay for a high-volume service hosted by MapQuest, or run MapQuest software on its own server. The road on the screen looked simple; the machinery and contracts behind it had several owners.

Tripod Gave Away Homepages. Lycos Bought the Builder Before Its Licensable Version Reached Beta.
By 1998, Tripod's members could publish pages for free with working tools. Lycos acquired the service, its audience and a much larger plan: package an advanced builder for other companies. The live pages and the unfinished product were different assets, with different risks.

First Internet Bank Needed a Bank Approval. The Internet Was the Delivery Route.
The First Internet Bank Needed a Bank Approval. The Internet Was the Delivery Route.
Security First Network Bank opened for online business in 1995. Its regulator's record drew a line that the “virtual bank” label blurred: approval was needed to create the bank, while the Internet was a way for that bank to serve customers.

Adobe Gave Flash Three Years to Leave. Its Player Shut the Door Twelve Days After Support Ended.
The deadline that killed ordinary Flash playback was later than the deadline that ended Adobe's support. Browser makers kept their own calendars. A creator could still have the file and lose the means of showing it.

SourceForge Called GIMP-Win Abandoned. GIMP Asked for Its Old Address Back.
GIMP moved its Windows installer to its own server. Old links kept sending people to SourceForge, where the host controlled the project page and tested a downloader carrying additional software. In 2015, the fight was over who could speak through an address the project had left behind.

PICS Made Web Ratings Portable. Parents Still Had to Choose Whose Judgment Counted.
PICS made a rating from one service readable to another company’s filtering software. It left the rating vocabulary and the blocking rules outside the standard, so a parent still had to choose which service, threshold and unrated-page rule to trust.

Google Reader Shut Down July 1. The Data Recovery Deadline Was July 15.
Google Reader went dark on 1 July 2013. A farewell and FAQ posted the next day said Google would no longer recover its subscription data after 15 July. RSS feeds had a life outside Reader; the reading history built inside it ran on Google's clock.

Gmail Offered 1 GB of Storage. Its Ads Matched Message Text.
Gmail’s launch pitch was an archive you could keep and search instead of pruning. The same mailbox also supplied words for contextual ads; in 2017 Google removed message content from ad personalization while keeping the service’s other bargain intact.

DigiCash Hid the Purchase. Mark Twain Bank Still Mailed the Password.
DigiCash’s 1995 eCash design promised a striking separation: the bank could issue real-dollar digital coins without being able to match a later spent coin to the customer’s withdrawal. The bank still ran the account, signed the money and redeemed it. One part of the launch arrived by post.

Prodigy Moderated Its Board. A New York Judge Called It a Publisher.
Prodigy sold families on a cleaner online forum. In 1995, a New York trial judge treated that editorial hand as the reason the service could face publisher liability for a user’s post. Congress made the clash a case for changing the rules.

The Search Was Free. Lycos’s New Company Had to Be in Pittsburgh.
