ICQ

~ the story ~

On June 26, 2024, after twenty-eight years of operation, the ICQ servers were turned off. The world's first widely-used internet instant messenger, the program that taught a generation what a "buddy list" was, the application that gave us the most viscerally rewarding notification sound in computing history, gone.

ICQ was made in 1996 by four Israeli developers in Tel Aviv. The name was a phonetic spelling of "I seek you." It launched in November 1996 with a simple promise: tell us a few things about yourself, get a number, find your friends.

By 1998 it had 12 million users. AOL bought the company that year for $407 million in stock plus $120 million performance contingencies. Eight years later, AOL gave up and sold ICQ to Mail.ru (Russia) for $187.5M, and mail.ru kept it alive, mostly out of stubbornness, until April 2024 when they finally announced the shutdown.

~ what made it special ~

Three things separated ICQ from everything else in the late 90s:

The number: Your ICQ identity was a number, not a username. Early adopters had short ones, six digits, five digits, sometimes four. The number was a status symbol. People paid money on eBay for low-numbered ICQ accounts. Your ICQ number meant: "I was here early." It was LinkedIn flex before LinkedIn existed. The flower: The little flower icon. Green meant online. Red meant unavailable. Yellow meant "free for chat." Watching your friends' flowers bloom and wilt across the day was an early form of digital telepathy. The sound: The "uh-oh" that played when a new message arrived was probably the most addictive notification sound ever designed. It triggered an immediate dopamine hit. People became Pavlovian, and to this day, if you play it for someone over 35, they will physically flinch and reach for their pocket.

The story of ICQ's death is the story of mobile. In 2007 the iPhone shipped. In 2009 WhatsApp launched. In 2011 BlackBerry's BBM had its peak and then collapsed. By 2012, Facebook had bought Instagram and was quietly building Messenger into a separate app. ICQ's desktop-first model - AOL's model; couldn't translate.

ICQ tried. Mail.ru launched mobile clients. They added voice, video, group chats, stickers, bots. They even added a feature where you could call a phone number from ICQ; none of it mattered. Network effects had moved.

By 2020 it was effectively a Russian-language messenger with international users in a few specific niches: long-running role-playing communities, stamp collectors, certain forums of the German-speaking technical underground. It was kept alive by Mail.ru as a sentimental project until the war and the sanctions made even that uneconomical.

~ the hole it left ~

ICQ taught us several things that we have since unlearned and would benefit from relearning:

That a contact list could be small and intentional. ICQ buddy lists rarely went above 50 people. You added someone with deliberation. The economy of attention was native to the protocol.

That presence could be ambient. The status-message field above your username was a poem, a song lyric, an inside joke updated through the day. It was an ambient broadcast, much closer to what we now call "stories" but with no algorithm and no expiration.

That identity could be a number. There is something pleasingly inhuman about being known as 14739204. Your number didn't say anything about your real name, your face, your job. ICQ was unsearchable. The closest modern analogue is the SoMe handle; but a handle is a brand. A number is a fingerprint.
