This is the <a href="https://en.wikipedia.org/wiki/Canadian_Broadcasting_Corporation" class="extiw" title="w:Canadian Broadcasting Corporation">Canadian Broadcasting Corporation</a>'s current corporate logo. The red "gem", adopted by the CBC in <a href="https://en.wikipedia.org/wiki/1992" class="extiw" title="w:1992">1992</a>, is a simplified version of the corporation's logo used between <a href="https://en.wikipedia.org/wiki/1974" class="extiw" title="w:1974">1974</a> and 1992.  The logo was simplified to improve its visibility on analogue <a href="https://en.wikipedia.org/wiki/Television" class="extiw" title="en:Television">television</a> screens.  The logo's simplification also made reproduction easier, as it is made up of only 13 geometric sections, as opposed to 25 in the <a href="https://en.wikipedia.org/wiki/Image:CBC_Logo_1974-1986.svg" class="extiw" title="en:Image:CBC Logo 1974-1986.svg">previous logo</a>.  The full corporate logo has the legends "CBC" and "Radio-Canada" on each side of it, in the <a href="https://en.wikipedia.org/wiki/Frutiger" class="extiw" title="w:Frutiger">Frutiger</a> typeface.  For the first several years of its use, the accompanying font appeared in heavy bold and used "SRC" in place of "Radio-Canada".
