Entertainment is an action, event or activity that aims to entertain, amuse and interest a public ("public" can consist of one person). This audience can have a passive role, as in the case of a play, a show on a TV or a movie, or active, as in the case of a video game. The holidays, games, reading and viewing works of art are not generally considered entertainment, but rather as a pastime. for the entertainment generally requires that the supplier of the show is visible to the viewer, with the exception of video games. The entertainment can attract an audience and influence their actions and thoughts. Active forms of amusement, such as sports, are more often considered to be recreation Activities such as personal reading or practicing a musical instrument are considered to be hobbies or pastimes.
Entertainment may also provide fun, enjoyment and laughter. The industry that provides entertainment is called the entertainment industry. There are many forms of entertainment for example: cinema, theatre, sports, games and social dance. Puppets, clowns, pantomimes and cartoons tend to appeal to children, though many adults may also find them enjoyable.
Television (TV) is a telecommunication medium for transmitting and receiving moving images that can be monochrome (black-and-white) or colored, with or without accompanying sound. "Television" may also refer specifically to a television set, television programming, or television transmission.
The etymology of the word has a mixed Latin and Greek origin, meaning "far sight": Greek tele (τῆλε), far, and Latin visio, sight (from video, vis- to see, or to view in the first person).
Commercially available since the late 1920s, the television set has become commonplace in homes, businesses and institutions, particularly as a vehicle for advertising, a source of entertainment, and news. Since the 1970s the availability of video cassettes, laserdiscs, DVDs and now Blu-ray Discs, have resulted in the television set frequently being used for viewing recorded as well as broadcast material. In recent years Internet television has seen the rise of television available via the Internet, e.g. iPlayer and Hulu.
Although other forms such as closed-circuit television (CCTV) are in use, the most common usage of the medium is for broadcast television, which was modeled on the existing radio broadcasting systems developed in the 1920s, and uses high-powered radio-frequency transmitters to broadcast the television signal to individual TV receivers.

The broadcast television system is typically disseminated via radio transmissions on designated channels in the 54–890 MHz frequency band.[1] Signals are now often transmitted with stereo or surround sound in many countries. Until the 2000s broadcast TV programs were generally transmitted as an analog television signal, but in 2008 the USA went almost exclusively digital.

A standard television set comprises multiple internal electronic circuits, including those for receiving and decoding broadcast signals. A visual display device which lacks a tuner is properly called a video monitor, rather than a television. A television system may use different technical standards such as digital television (DTV) and high-definition television (HDTV). Television systems are also used for surveillance, industrial process control, and guiding of weapons, in places where direct observation is difficult or dangerous.

By 2012 the development of broadband enabled the integration of the internet and Web 2.0 features into modern television sets and set-top boxes, as well as the technological convergence between computers and television. Such TVs are called smart TV's or "connected TV", which is the biggest current innovation in consumer electronics.
