Founded in 1999 and controlled by the Shaw family, Corus Entertainment is one of the "Big 3" broadcasting companies in Canada (alongside Rogers and Bell Media). In addition to the Global Television Network and their radio station group, Corus owns a portfolio of brands that mainly target women, children, and families: including animation studio Nelvana and publisher Kids Can Press.
Corus was first created as a spin-off of Shaw Communications' media assets. Shaw later acquired Canwest when they went bankrupt in 2010, and operated their assets as Shaw Media. Shaw Media itself was composed of assets that were previously owned by Canwest, as well as firms acquired by Canwest, including assets from Western International Communicationsnote and Alliance Atlantisnote On April 1, 2016, Shaw Media was re-organized and merged into Corus Entertainment in exchange for cash and stock to budget Shaw Communications's purchase of the wireless carrier Wind Mobile. To reflect this, Corus adopted a new logo for the first time since its inception in 1999.
