ICQ

From open-encyclopedia.com - the free encyclopedia.

ICQ is the first instant messaging computer program created by start-up Israeli company Mirabilis and first released in November, 1996. The name ICQ is a play on the phrase "I seek you".

In June 2004 ICQ celebrated its 300 millionth download from download.com where it remained the number 1 most popular download for 7 consecutive years.

ICQ was founded by Yair Goldfinger, Arik Vardi, Sefi Vigiser and Amnon Amir and managed by Ariel Yarnitsky.

ICQ allows the sending of text messages, URLs, multi-user chats, file transfers, greeting cards and more.

ICQ users are identified by numbers called UIN, distributed in sequential order (though it is rumored there are gaps in the sequence). New users are now given a UIN of well over 100,000,000, and low numbers (six digits or less) have been auctioned on eBay by users who signed up in ICQ's early days.

AOL acquired Mirabilis and ICQ in 1998.
