A skyline is the outline or shape created by a city's overall structure, or by human intervention in a non-urban setting or in nature that is formed where the sky meets buildings or the land. City skylines serve as a pseudo- fingerprint as no two skylines are alike. For this reason, news and sports programs, television shows, and movies often display the skyline of a city to set a location. The term The Sky Line of New York City was first introduced in 1896, when it was the title of a color lithograph by Charles Graham for the color supplement of the New York Journal. 
Stonehenge's skyline has been known for millennia.
Some natural skylines have been unintentionally modified for commercial purposes.

Towers from different eras make for contrasting skylines.
Some remote locations have striking skylines, created either by nature or by sparse human settlement in an environment not conducive to housing significant populations.
Skylines are sometimes used as backgrounds for movies, television shows, news websites, and in other forms of media.
Several services rank skylines based on their own subjective criteria. Emporis is one such service, which uses height and other data to give point values to buildings and add them together for skylines.

When Charles Graham's view of New York was published, the new term used in the title, "sky line," caught on immediately.
