A group of private investors and Banque National have invested close to $1 million in Montreal post/digital-effects house Groupe Image Buzz. Buzz president Gilles C. Massicotte says the financing will be used for technological upgrades. The investment marks a clear turnaround for the company, which was in financial difficulty in ’97 following an unsuccessful entry into the u.s. market. Buzz shareholders include Capital Communications c.d.p.q., a subsidiary of the Caisse de depot et placement du Quebec.
