The answer to that question is…NO or at least the origins of Valentine’s Day is not a marketing concoction. As described by the Virtual Museum of Canada (click here), the origins of the holiday can be traced back to the life of a Christian saint and an ancient Roman festival. Wikipedia is also always useful and does a more extensive background on the Saint that burned at the stake on February 14th (click here).
