Ticker tape parades: A uniquely New York phenomenon
Most people these days are far less familiar with ticker tape as it was meant to be used, and far more familiar with it as street litter. That's because New Yorkers often celebrated with whatever they had around them. In the case of lower Manhattan, what they had happened to be ticker tape.
The first ticker tape parade was a spontaneous celebration of the dedication of the Statue of Liberty in 1886. Office workers noticed that when tossed out the window, their ticker tapes made a dramatic, showy swirling motion worthy of such an occasion, and it became an unofficial way to celebrate a lot of things.
In 1919, the first official ticker-tape parade took place to welcome soldiers home from World War I. From there, they became regular events, with papers flying out of Manhattan windows to help punctuate the celebratory environment of the parades through the streets. But, by the 1960s, ticker tape parades were becoming far more of a common nuisance than an over-the-top celebration, so were officially limited to specific and special occasions.
Today, you'll still see the odd ticker tape parade along the Canyon of Heroes, but it's done using shredded recycled paper instead of actual ticker tapes.
