Parade History

According to the New York Tourist Commission, the inaugural Macy's Day Parade took place on Christmas, 1924, and had an audience of 250,000 people. No giant balloons until 1927 when Felix the Cat showed up. The parade was first broadcast on radio in 1932.

The balloons are filled with 12,000 cubic feet of helium. They are inflated on the Wednesday before Thanksgiving at the American Museum of National History from 3 p.m. -10 p.m.

While it may be the most famous, it isn’t the oldest Thanksgiving parade. The oldest one is the Thanksgiving Day Parade in Philadelphia.
