quote: BBM -- the company -- had a rich history. It was founded in 1944 as the Bureau of Broadcast Management to help network and advocate for television broadcasters and advertisers. It later changed its name BBM Bureau of Measurement and then BBM Canada. Today it holds and actively operates out of the domain name bbm.ca, uses "BBM" in its logo, and operates employee email from a bbm.ca address.
