The middle of the 1990s was marked by the inclusion of bisexuals as a represented group within the gay community, when they successfully sought to be included on the platform of the 1993 March on Washington for Lesbian, Gay and Bi Equal Rights and Liberation. Transgender people also asked to be included, but were not, though trans-inclusive language was added to the march's list of demands. The transgender community continued to find itself simultaneously welcome and at odds with the gay community as attitudes about non-binary gender discrimination and pansexual orientation developed and came increasingly into conflict. In 1994, New York City celebrated "Stonewall 25" with a march that went past the United Nations Headquarters and into Central Park. Estimates put the attendance at 1.1 million people. Sylvia Rivera led an alternate march in New York City in 1994 to protest the exclusion of transgender people from the events. Attendance at LGBT Pride events has grown substantially over the decades. Most large cities around the world now have some kind of Pride demonstration. Pride events in some cities mark the largest annual celebration of any kind. The growing trend towards commercializing marches into parades—with events receiving corporate sponsorship—has caused concern about taking away the autonomy of the original grassroots demonstrations that put inexpensive activism in the hands of individuals.
