In Montreal, four brothers founded a photo company, Angreen Photo Inc., which became the jumping off point for what was to become Astral Media, owner of the largest group of radio stations in Canada, with additional major ownerships in both conventional and specialty television channels. The brothers, Harold, Harvey, Sidney and Ian Greenberg, would each have significant contributions to make to the evolution of this exceptional company.
Pendant de nombreuses années, Shaw Cablesystems gérait avec succès ses divers systèmes de câblodistribution. Le 27 août 1987, en faisant l’acquisition de deux stations situées à Red Deer (Alberta), CIZZ-FM et CKGY-FM, Shaw (qui deviendra plus tard Corus Entertainment) effectuait son entrée en scène en tant que titulaire de licences d’entreprises de radiodiffusion en direct. Au cours de cette même période, Shaw effectuait d’autres acquisitions, dont celles de CISN-FM Edmonton (1988), CHAY-FM Barrie (1990), CKCK-FM Woodstock (1991) et CFOX-FM et CKLG-AM Vancouver (1992).
With the acquisition from Roy (later Lord) Thomson of Abitibi Témiscamingue AM radio stations CKRN Rouyn, CHAD Amos and CKVD Val d’Or, brothers Jean-Joffre and David Armand Gourd, together with Roger Charbonneau, became owners of what was to become a major Quebec radio and television station group, Radio Nord (which would later become RNC Media). The stations were supplementary affiliates of CBC Quebec.
