NEW YORK — Hundreds of thousands of people donning rainbow attire filled the streets of New York City for the annual gay pride parade Sunday afternoon.

Organizers of San Francisco's Lesbian, Gay, Bisexual and Transgender Pride Parade, just called "Pride," expect about 1 million revelers.

British actor Sir Ian McKellan served as New York's grand marshal for the festivities.

Four years ago, about 2-million people lined Manhattan streets to celebrate gay marriage becoming legal in New York state. That was the record high.

But after Friday’s Supreme Court Decision legalizing gay marriage nationwide, organizers say attendance at this years march could reach well beyond that.

In honor of the first marchers, it is not called a parade.

In 1970, activists did not seek permits when they took the streets on the first anniversary of the Stonewall riots.

What would become an annual march began as an attempt to transform how the country felt about gay people, when coming out could jeopardize careers, friendships and families.

The march's original purpose, showcasing gay power and pride and the fight for equality, is not forgotten.

Gov. Andrew M. Cuomo kicked off Sunday's New York City Pride celebration by officiating a same-sex wedding in front of the Stonewall Inn.

Former Olympian  Caitlyn Jenner was spotted celebrating pride at the Dream Downtown Hotel in Chelsea.
