Om Malik must be a happy man today after Ludicorp Research & Development Ltd. was acquired by Yahoo Inc. - a deal disclosed/predicted by Om, who wrote about the company last year in Business 2.0. Vancouver-based Ludicorp makes popular photo-sharing software called Flickr, which lets people share photos on the Internet. Flickr, which was started by the husband-and-wife team of Stewart Butterfield and Caterina Fake, is particularly popular with bloggers because you can "tag" photos and then easily share images with other people. Yahoo apparently scrouged up some loose change of US$30-million to US$35-million for Ludicorp, which can now be added to the growing list of North of the Border (NOTB) technology companies snapped up by cash-rich U.S. players.
