Television is a telecommunication medium used for transmitting sound with moving images in monochrome (black-and-white), or in colour, and in two or three dimensions. It can refer to a television set, a television program, or the medium of television transmission. Television is a mass medium, for entertainment, education, news and advertising.
Television became available in crude experimental forms in the late 1920s. After World War II, an improved form became popular in the United States and Britain, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in the US and most other developed countries. The availability of storage media such as VHS tape (1976), DVDs (1997), and high-definition Blu-ray Discs (2006) enabled viewers to watch recorded material such as movies. At the end of the first decade of the 2000s, digital television transmissions greatly increased in popularity. Another development was the move from standard-definition television (SDTV) (576i, with 576 interlaced lines of resolution and 480i) to high-definition television (HDTV), which provides a resolution that is substantially higher. HDTV may be transmitted in various formats: 1080p, 1080i and 720p. Since 2010, with the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through services such as Netflix, iPlayer, Hulu, Roku and Chromecast.
An author is broadly defined as "the person who originated or gave existence to anything" and whose authorship determines responsibility for what was created. Narrowly defined, an author is the originator of any written work and can also be described as a writer.
In copyright law, there is a necessity for little flexibility as to what constitutes authorship. The United States Copyright Office defines copyright as "a form of protection provided by the laws of the United States (title 17, U.S. Code) to authors of "original works of authorship". Holding the title of "author" over any "literary, dramatic, musical, artistic, [or] certain other intellectual works" give rights to this person, the owner of the copyright, exclusive right to do or authorize any production or distribution of their work. Any person or entity wishing to use intellectual property held under copyright must receive permission from the copyright holder to use this work, and often will be asked to pay for the use of copyrighted material. After a fixed amount of time, the copyright expires on intellectual work and it enters the public domain, where it can be used without limit. Copyright law has been amended time and time again since the inception of the law to extend the length of this fixed period where the work is exclusively controlled by the copyright holder. However, copyright is merely the legal reassurance that one owns his/her work. Technically, someone owns their work from the time it's created. An interesting aspect of authorship emerges with copyright in that it can be passed down to another upon one's death. The person who inherits the copyright is not the author, but enjoys the same legal benefits.
