Because two days ago it was Saint Patrick’s Day, I found this interesting article in Mashable about Guinness beer and its ads. Guinness is basically the national drink in Ireland. For more than 250 years, the company has been brewing beer in Dublin. While the brand is known for its classic Irish Extra Stout, the company also makes a draught stout and a black lager. Of course, Guinness is also the official drink of St. Paddy’s Day, getting the party going all across the world.
