Just About Every Brand Wants a Slice of Pi Day

If you've spent 3.14 seconds on Twitter or Facebook today, you probably know that it's March 14, or 3.14, or Pi Day. 

Ah yes, Pi Day, celebrating a mathematical constant, a number with way too many decimal places, a number used to calculate the diameter, radius and circumference of a circle.

It's also a number that seems to inspire brands to create a wide range of pi/pie-related social media updates. From the obvious pizza and bakery brands to the slightly more tangential tech brands, there's been quite a bit of fun and questionably topical output on social media this morning.

AT&T commendably tied its post back to actual science education:

Getting kids interested in #STEM should be easy as #Pi. #PiDayhttp://t.co/fXlKKDenvLpic.twitter.com/IIJEHCWF6L— AT&T (@ATT) March 14, 2014

Bing got pretty serious with its decimal dedication:

Happy 3.141592653589793238462643383279502884197169399375105820974944592 307816... Day. http://t.co/0BVx1aXVDK#pidaypic.twitter.com/v0l5KH0Ny8— Bing (@bing) March 14, 2014

And even Red Bull was true to the math:

But a lot of brands just wanted to cover Rebecca Black's "Friday:"

It's Pi Day, Pi Day gotta get down on Pi Day. #HappyPiDay

Then there was a lot of the usual branded oddness:

RT if you're 3.14 times more excited to eat a pie today. #PiDay.

— Domino's Pizza (@dominos) March 14, 2014

Eat pie for breakfast! While you’re at it, why not make it a low calorie Tasti Mud Pie flavor? Happy Pi Day to all our Tasti lovers.
