Book excerpt: Canadian Newspaper Ownership in the Era of Convergence investigates the current state of Canada's newspaper industry in light of recent developments-increasing concentration of ownership, multi-media convergence, and controversy over the actions of proprietors. Case studies examine how Conrad Black's acquisition of newspapers in the mid-1990s, bringing his total ownership to over half of the country's dailies, followed by the subsequent purchase of the most important of these by CanWest Global, has actually influenced the content of newspapers. Canadian Newspaper Ownership revisits "social responsibility" in the context of the changed media landscape as a means of prescribing how newspaper owners and employees might conduct themselves in the public interest.
