The Foundation for Democratic Advancement did an overview of media ownership in the course of a paper on media coverage of elections in 2012; this found that the majority of the daily newspaper market in Alberta in controlled by two companies Postmedia (64.8%) and Quebecor/Sun Media (24.9%). A different measure of media concentration was used for broadcasting in the same study, that of ownership of stations (including stations with no news content), rather than by ratings. The largest radio company was Newcap Broadcasting which owned 32 of 92 total stations, Rogers Media owned 14, and James A. Pattison owned nine. In television, the largest companies were Bell Media with four stations, Rogers with four, Shaw Media with three, and the CBC with three (two English-language, one French).
In 1937, the Social Credit government of Wiliam Aberhart passed the Accurate News and Information Act which forced newspapers to print "corrections" to stories the government objected to, and would require the papers to reveal their sources in the case of statements against the government. This bill became part of a constitutional crisis between the lieutenant governor and the federal government on one side, and the Social Credit government (especially its radical wing represented by the Social Credit Board) on the other. This led to the Reference re Alberta Statutes case in the Supreme Court which ruled the act to be ultra vires (unconstitutional). As well the Edmonton Journal won a special Pulitzer Prize for Press Freedom for fighting against the law, the only non-American newspaper ever to have done so.
