Nokia announced today that it has completed its acquisition of Plazes (www.plazes.com), a privately-owned start-up company of 13 people with its principal operations in Berlin. The deal was initially announced on June 23, 2008.

By acquiring Plazes, Nokia will extend its context-based service offering with social presence and time-based activity planning features. Plazes adds the elements of “place” and “time” to social networking through features that allow people to alert friends of their activity and location; review their own and others’ past activities; share their experiences and make plans with friends, who are then able to respond with comments and suggestions as well as their own location information.
