The TKTS ticket booths in New York and London sell Broadway and Off-Broadway shows, music and dance events and West End theatre tickets, respectively, at discounts of 25–50% off the face value.
New York City's TKTS (pronounced "Tee-Kay Tee-Ess", not "tickets") first opened in 1973 and is operated by the Theatre Development Fund. There are three locations: one in Duffy Square (at 47th Street and Broadway, the north end of Times Square); another at South Street Seaport in Lower Manhattan (replacing the office formerly located in the lobby of the World Trade Center, which was destroyed in the September 11, 2001 terrorist attacks); and a third in Downtown Brooklyn (Jay St. and Myrtle St. Promenade). The Times Square booth sells day-of-performance tickets only, while the South Street Seaport booth sells tickets to evening performances on the day of the performance and matinee tickets the day before.
