Nightlife is the collective term for any entertainment that is available and more popular from the late evening into the early hours of the morning. It includes the public houses, nightclubs, discothèques, bars, live music, concerts, cabaret, small theatres, small cinemas, shows, and sometimes restaurants present in a specific area. These venues often require cover charge for admission, and make their money on alcoholic beverages. Nightlife encompasses entertainment from the fairly tame to the risque to the seedy. Nightlife entertainment is inherently edgier than daytime amusements, and usually more oriented to adults, including "adult entertainment" in red-light districts. People who prefer to be active during the night-time are called night owls.
In the United States 
Nightlife legislation of the United States was created after the 2006 murders of Imette St. Guillen and Jennifer Moore, after which American teenagers' use of fake IDs to obtain access to nightclubs was brought to attention.
