The 88-Year Evolution Of The Macy's Thanksgiving Day Parade

Every year, 3.5 million people flock to New York City to see the parade march down a two-and-a-half mile stretch of Manhattan.

Another 50 million people gather around their television sets to watch the event from home.

What began as a small Macy's employee-run event called Macy's Christmas Parade, has morphed into a huge production that requires almost an entire year's worth of preparation.

Macy's 88th Annual Thanksgiving Day spectacle will feature appearances from Idina Menzel, KISS, and The Vamps. Six new balloons including Paddington Bear will make their debut in the parade.
