Numeris

Canadian audience measurement organization
Numeris (formerly the Bureau of Broadcast Measurement, or BBM Canada) is a Canadian audience measurement organization. Established on May 11, 1944 as a division of the Canadian Association of Broadcasters, Numeris is the sole provider of viewership numbers for television and radio broadcasters in Canada.

Numeris was founded by the Canadian Association of Broadcasters on May 11, 1944 as the Bureau of Broadcast Measurement. In 1964, it became the first ratings service in the world to introduce computerized sample selection. In 2004, the organization began a joint venture with Nielsen Media Research to adopt its Portable People Meter system for television audience measurement. The suit was dismissed in 2012 by Canadian federal courts as being without merit. BBM Canada ultimately chose to adopt a different name. On August 28, 2022, Numeris ceased publication of TV Topline Reports.

In radio, Numeris is the main provider of ratings services. The company has traditionally used a diary based system for tracking radio audience habits and this system is still used in most markets. In Montreal, Toronto, Vancouver, Edmonton and Calgary ratings are now measured using the Portable People Meter (PPM) technology.

In television, Numeris is partnered with the American company Nielsen in a joint venture which measures the Toronto, Vancouver, Calgary, Edmonton, Montreal Anglo and Montreal Franco markets, the Ontario region and national ratings figures via Portable People Meters. Numeris is the senior partner in the joint venture, and also continues to independently monitor some markets — primarily the francophone television market in Quebec, and some smaller media markets — which are not served by the joint operation, through diaries.
