Big Ideas offers lectures on a variety of thought-provoking topics which range across politics, culture, economics, art history, science.... By nature of its lecture format, pacing and inquisitive approach, it is the antithesis of the prevailing sound-bite television norm. The simple, bold concept is a victory of substance over style. Big Ideas airs Saturdays and Sundays at 5:00 PM EST on TVO - Canada's largest educational broadcaster.
