BCE Inc, Canadas biggest telecom company, posted a 17 percent rise in adjusted quarterly profit on Thursday, helped by strong growth in its media wing and ongoing strength in wireless. The Montreal-based parent of Bell Canada said fourth-quarter net earnings slipped to C$495 million, or 64 Canadian cents a share, from C$666 million, or 86 Canadian cents, a year earlier, due to a windfall on spectrum in late 2012.
