Media and Internet Concentration in Canada 1984 – 2017

Public Deposited
  • Part of a series from the CMCRP - visit the CMCRP website for additional background. See also the related overview Poster - Canada’s Top Media, Internet & Telecom Companies by Market Share (2017) The workbook and reports were revised in early January 2019 to replace estimated revenue values for the mobile wireless, internet access and internet advertising markets with published final revenue figures from the Canadian Radio-television and Telecommunications Commission (CRTC) on December 21, 2018 and by the Internet Advertising Bureau of Canada on December 10, 2018.

Resource Type
  • This report examines the state of competition in the mobile wireless market, internet
    access, broadcast, pay and streaming TV services, internet advertising, advertising
    across all media, newspapers, browsers, online news sources, search, social media,
    operating systems, etc. in Canada over the period from 1984 until 2017. We call the
    sum-total of these media “the network media economy”. We then use two common
    metrics—Concentration Ratios and the Herfindahl-Hirschman Index (HHI)—to determine
    whether these markets—individually and collectively—are competitive or concentrated.
