Soho is an area of the City of Westminster and is part of the West End of London. Long established as an entertainment district, for much of the 20th century Soho had a reputation as a base for the sex industry in addition to its night life and its location for the headquarters of leading film companies. Since the 1980s, the area has undergone considerable gentrification. It is now predominantly a fashionable district of upmarket restaurants and media offices, with only a small remnant of sex industry venues.
