Electric Park was a name shared by dozens of amusement parks in the United States that were constructed as trolley parks and owned by electric companies and streetcar companies.[1] After 1903, the success of Coney Island inspired a proliferation of parks named Luna Park and Electric Park,[2][page needed] while the World's Columbian Exposition of 1893 inspired the formation of White City amusement parks at roughly the same time. The existence of most of these parks was generally brief: the bulk of them closed by 1917, the year of the United States' entry into World War I. Many pavilions have outlasted the parks themselves, with a few of them still standing today.
