Here's an interesting graphic:
Search trends for "Irish Whiskey", "Scotch Whisky"
It shows the search volume for each term on Google's servers over the last few years. There is a spike of interest before Christmas for both Irish and Scotch but also a massive spike for Irish alone around St Patrick's Day.
It's useful, perhaps, for the society in its promotional activities - there is search traffic to be captured every March. But we might also view it as a challenge - to encourage people to think about Irish whiskey at other times of the year too.
