Yahoo! just announced they have acquired events site Upcoming.org and the three-man team of Andy Baio, Gordon Luk, and Leonard Lin. Upcoming is an events message board for individuals and companies, providing a way to publicize and discover events. Upcoming has a database of venues supplied by users, tags for events, as well as information about what events its members are attending and watching. Upcoming recently added a groups feature to allow private events and recurring distribution lists.
Upcoming and its team will be integrated with Yahoo! Local. Yahoo! Local has a database of venues complete with reviews and merchant supplied data. Yahoo! Groups is a launchpad for interest groups and could benefit from better integration with event and venue information provided by the new Yahoo! Local. I expect Yahoo! 360 will add a list of events a member is watching or attending to its user information offerings within the next few months.
