ICQ still exists, and is still updated regularly. This allowed America Online to have a virtual hegemony over instant messaging until Google Talk and MSN Messenger began grabbing market share. In 1998, only two years after the creation of ICQ, America Online acquired the program from Mirabilis for $407 million, in spite of it having no revenue at all. In 1997, America Online released its graphical instant messenger, AIM.

Five and six digit UINs are often seen for sale on eBay, allowing newer ICQ users to acquire an older UIN. Since UIN numbers increase sequentially as new users are added, in some circles the length of a person’s ICQ number is looked at as a sign of online “street cred.” A user with a five digit UIN, for example, is obviously an early adopter, as they were one of the first hundred-thousand users. This allows an ICQ user to change every piece of information about their account - screen name, email address, real name, home town - and still have the same primary identification. Rather than making use of unique screen identities chosen by the user, as AIM uses, or using the user’s email address, as MSN Messenger and Google Talk use, ICQ instead created a unique identification number (UIN) for each user. There was a time when ICQ was by far the dominant instant messenger client in existence, and for many companies during the dot-com years it was a preferred mode of communication between them and customers. It was the first instant messenger client to truly use a graphical user interface (GUI), and was easy to install and use for almost anyone. ICQ was an innovator in the field of instant messaging. ICQ and other messaging programs make use of various emoticons to convey simple emotions. The company relied very little on traditional marketing, instead depending on the viral effect as customers told their friends about it, and their friends in turn told their friends. Mirabilis was funded primarily by one of the founder’s fathers, as well as other small investors. In 1996, an Israeli company called Mirabilis released their instant messaging product: ICQ.
