This week, Twitter set a new record and also celebrated #NationalDonutDay, #WorldEnvironmentDay and #NationalRunningDay.

Twitter was a huge source of news this week. On Monday, #CallMeCaitlyn broke President Obama's record by gaining one million followers in just over four hours. After that, Twitter took a run for #NationalRunningDay, cleaned up its act for #WorldEnvironmentDay, and had a delicious finish with #NationalDonutDay.

For most people, Friday is the best workday, but this week #NationalDonutDay made Friday even better after the largest donut chain in the U.S., Dunkin' Donuts, began the day with a special offer: a free donut with any beverage purchase.

Athletic equipment brand ASICS celebrated #NationalRunningDay by giving away shoes.

Fitbit was smart to leverage user-generated content.

Twitter also lit lip in celebration of @Caitlyn_Jenner's debut earlier this week. After gaining more than a million followers in around four hours, Jenner broke Twitter records and trans rights barriers.
