(Page 2 of 2)

“The digital industry has grappled with the differences between panel and server information for many years,” said Graham Mosey, SVP and General Manager, CanWest Digital. “We were one of the first comScore clients to support the Media Metrix 360 project because we saw the obvious benefits. The comScore-Omniture partnership eliminates the implementation burden and will expedite the expansion of this new form of measurement. Having as many publishers as possible involved can only be good for the industry. This is a groundbreaking development which is extremely exciting.”
