New York - Nielsen/NetRatings, a provider of Internet media audience measurement and market research, announced on Monday the launch of VideoCensus, an online video measurement service that combines panel and census research methodologies. To facilitate reporting, online video publishers attach a piece of NetRatings code to their video delivery platforms, which then allows NetRatings to collect a precise census count of viewing activity. The service will also factor in data from NetRatings desktop meters, deployed on thousands of users' PCs worldwide.
