Context: Coney Island USA is a 501(c)(3) not-for-profit arts organization founded in 1980 that is dedicated to the cultural and economic revitalization of the Coney Island neighborhood of the Borough of Brooklyn in New York City.  Its landmark building in the heart Coney Island's amusement district houses a theater in which the organization presents "Sideshows by the Seashore", a showcase for performers with unusual talents that runs continuously during the warmer months, as well as the Coney Island Museum.  It is also notable as the organizer of the annual Coney Island Mermaid Parade, the first of which took place in 1983. Stillwell Avenue is a major two-way north/south thoroughfare in southern Brooklyn and the central section of Coney Island.  It is 2.4 miles (3.86 kilometres) long and begins at a dead end on Coney Island.  The road goes north, leaving Coney Island, ending at Bay Parkway, where the road continues as the Bay Ridge Parkway (former Route 439).  On December 11, 2008 it acquired the subsidiary name Polar Bear Club Walk, named for the Coney Island Polar Bear Club.

Steeplechase Park was an amusement park in the Coney Island area of Brooklyn, New York created by George C. Tilyou (1862–1914) which operated from 1897 to 1964.  It was the first of the three original iconic large parks built on Coney Island, the other two being Luna Park (1903) and Dreamland (1904).  Steeplechase was Coney Island's longest lasting park.  Unlike Dreamland, which burned in a fire in 1911, and Luna Park which, despite early success, saw its profitability disappear during the Great Depression, Steeplechase had kept itself financially profitable.  The Tilyou family had been able to adapt the park to the changing times, bringing in new rides and new amusements to Steeplechase such as the Parachute Jump.

Gone to Coney Island and Booming Business are two 1910 American silent short comedy productions by the Thanhouser Company.  Both were released together on a single film reel on July 5, 1910.  "Gone to Coney Island" is a comedy that features Coney Island, which the mere subject would make for a successful film.  "Booming Business" may have been the very type of slapstick comedy that Edwin Thanhouser specifically said the Thanhouser Company would not produce.  The productions of both films have no credits for the cast or crew, but possible candidates for these roles exist.  Reviews of the films favored "Gone to Coney Island", but some reviewers specifically refused to explain the plot because Coney Island subjects were deemed self-explanatory.  "Booming Business" received one detailed review in "The New York Dramatic Mirror" which was negative.  The films are presumed lost. KBJ Architects, Inc.
