ICQ (chat) 1. Abbreviation for "I seek you".
2. A proprietary chat system created by a couple of israeli guys, who later founded "mirabilis". ICQ was sold to America On-Line around 1998. The name "ICQ" is a play on "cq", the radio signal for seeking conversation. http://icq.com/. [Confirm derivation? TCP? Summary?] Last updated: 2000-04-03
