The Globe and Mail reports in its Monday edition that Corus Entertainment has an implied market capitalization of $29-million, down from $2-billion at the end of 2014. Guest columnist Dvai Ghose writes that a TD report argues the equity value may be zero, given $1.1-billion of net debt. Corus's challenges stem from a combination of consistently bad regulatory decisions that have favoured giant content providers, such as Netflix, over domestic players: changing viewership, rising U.S. content costs, the questionable acquisition of Shaw Media in 2016, poor execution and a lack of substantial cost-cutting. Some of that is unique to Corus, but the most important part is not. Corus's woes point to a future of American media dominance and ever-shrinking Canadian content. Canadian companies have been particularly affected by regulations from the Canadian Radio-television and Telecommunications Commission designed, ironically, to protect Canadian content. Over time, Rogers Media and BCE's Bell Media may be the only significant Canadian media companies left, but this is owing to their rights to live sports and their behemoth parent companies. This in turn puts the future of Canadian content in a precarious position.
