Television program

distinguish|broadcast programming}}

A television program is a segment of content intended for broadcast on vision, other than a commercial, trailer, or any other segment of content not serving as attraction for viewership. It may be a single production, or more commonly, a series of related productions (also called a television series).

A television series that is intended to comprise a limited number of episodes may be called a miniseries or serial. Series without a fixed length are usually divided into seasons or series, yearly or semiannual sets of new episodes. While there is no defined length, US industry practice tends to favor longer seasons than those of some other countries.

A one-time broadcast may be called a "special," or particularly in the UK a "special episode." A television film ("made-for-TV movie" or "television movie"), is a film that is initially broadcast on television rather than released in theaters or direct-to-video.

A program can be either recorded, as on video tape, other various electronic media forms, played with an on-demand player or viewed on live television.

Arrow

An arrow is a shafted projectile that is shot with a bow. It predates recorded history and is common to most cultures. An arrow usually consists of a shaft with an arrowhead attached to the front end, with fletchings and a nock at the other.

History

The oldest evidence of stone-tipped projectiles, which may or may not have been propelled by a bow (c.f. atlatl), dating to c. 64,000 years ago, were found in Sibudu Cave, South Africa. The oldest evidence of the use of bows to shoot arrows dates to about 10,000 years ago; it is based on pinewood arrows found in the Ahrensburg valley north of Hamburg. They had shallow grooves on the base, indicating that they were shot from a bow. The oldest bow so far recovered is about 8,000 years old, found in the Holmegård swamp in Denmark. Archery seems to have arrived in the Americas with the Arctic small tool tradition, about 4,500 years ago.

Size

Arrow sizes vary greatly across cultures, ranging from eighteen inches to five feet (45 cm to 150 cm). However, most modern arrows are 75 centimetres (30 in) to 96 centimetres (38 in); most war arrows from an English ship sunk in 1545 were 76 centimetres (30 in). Very short arrows have been used, shot through a guide attached either to the bow (an "overdraw") or to the archer's wrist (the Turkish "siper"). These may fly farther than heavier arrows, and an enemy without suitable equipment may find himself unable to return them.
