"(2010) AOL has sold ICQ to Digital Sky Technologies (DST), Russia's largest Internet company, for US$187.5 million. DST's offer was apparently more attractive than those of Russia's ProfMedia and China's Tencent. ICQ, originally released in 1996 and bought by AOL in 1998 for US$407 million, was one of the world's first major instant messaging systems. Although largely forgotten in English-speaking countries, it remains widely popular in Central Europe, Russia, and Israel. Moscow News has additional coverage of the deal."
