St. Patrick’s Day is the holiday of the year for Irish companies, so naturally Twitter was a pot of gold of brand wishes and promotions on Thursday.
As a drinking holiday, beer and liquor companies were in their element. Jameson Irish Whiskey offered free drinks to UK customers.
Jameson also sponsored a Snapchat filter to celebrate the day.
Guinness has been counting down to St. Paddy’s Day all week and encouraging followers to use #GuinnessTache with photos of their foam mustaches.
Budweiser tweeted a video to remind followers they can drink something other than Irish beers and whiskeys this March 17.
The festivities weren’t confined to the Irish or alcohol companies. Many brands jumped on the #StPatricksDay hashtag, which had more than 400,000 tweets by noon.
Some companies promoted sales or specials.
Others just added a shade of green (or gold) to their usual Twitter messages.
