Facebook employees marching in San Francisco’s annual gay pride parade is nothing new – but CEO Mark Zuckerberg participating is something new.

At Sunday’s Pride Parade, Zuck led a giant crew of Facebook employees, more than 700, through the streets of downtown San Francisco. That’s more than 300 more employees than Facebook had last year, and more than 10 times as many participants the company sent back in 2011.

San Francisco’s Lesbian Gay Bisexual Transgender Pride Celebration has been held every year since 1972 (under a few different names over the course of the years). The celebration commemorates the famous Stonewall Inn rebellion in New York City’s Greenwich Village back in 1969. The celebration, which culminates in the Pride Parade, is one of the largest LGBT pride events in the world.

Of course, this year’s Pride Parade had a little bit of extra significance, considering the U.S. Supreme Court’s recent rulings on the unconstitutionality of the Defense of Marriage Act.

On that day, Zuckerberg had this to say on Facebook:

“I’m proud that our country is moving in the right direction, and I’m happy for so many of my friends and their families. #PrideConnectsUs”
