1924: Macy's employees, many of them first-generation immigrants, organized a parade modeled on the festivals they'd grown up with in Europe. It ran six miles, from 145th St in Harlem down to Herald Square and included live animals borrowed from the Central Park Zoo. It was called the Macy's Christmas Parade.
1927: The animals were retired in favor of balloons, Tom Turkey among the first. The event was renamed the Macy's Thanksgiving Day Parade.
1933: The parade had grown into one of the city's biggest annual gatherings, drawing crowds into the hundreds of thousands.
1945: The parade returned after the end of WWII and with it, a shorter route better suited to the crowds it now drew.
1947: Miracle on 34th Street used real parade footage, introducing the event to audiences who'd never set foot in New York.
1948: NBC broadcast the parade for the first time, beginning a run of national coverage that hasn't stopped.
2026: The 100th parade steps off from Central Park West, down 6th Ave, and into Herald Square, the same finish line it's had for a century.
