Blackboard has a habit of aquiring an education-technology company every year, but this year it bought not one but two companies—both of which offer similar services for holding online courses and virtual office hours.

Today Blackboard Inc. announced plans to buy Elluminate, based in Alberta, Canada, and Wimba, based in New York, both of which sell products that support online learning and student collaboration through online videoconferencing and audioconferencing tools. The sales must first be approved by the boards of both rivals. Blackboard plans to pay a total of $116-million for the pair.
