You mean Orkut. That was weird: it got wildly popular in Brazil, India, Turkey and other places, but never really took off in "the West" (weird name, bad quality when first released, boring UI...). I guess most of its members (it's still going!) will become G+ users, so it wasn't a complete failure in the end (in fact, a large userbase in developing countries is an insurance policy for the future, if you can keep it going).
EDIT: Wikipedia says "Orkut was quietly launched on January 22, 2004 by Google. Orkut Büyükökten, a Turkish software engineer, developed it as an independent project while working at Google. While previously working for Affinity Engines, he had developed a similar system, In Circle, intended for use by university alumni groups. In late June 2004, Affinity Engines filed suit against Google, claiming that Büyükkökten and Google based Orkut on In Circle code. The allegation is based on the presence of 9 identical bugs in Orkut that also existed in Circle."
