Television (TV) is a telecommunication medium for transmitting moving images and sound. Additionally, the term can refer to a physical television set rather than the medium of transmission. Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than "radio broadcasting," which refers to an audio signal sent to radio receivers.

Television became available in crude experimental forms in the 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, 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 U.S. and most other developed countries.

In 2013, 79% of the world's households owned a television set. The replacement of earlier cathode-ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED), OLED displays, and plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most television sets sold in the 2000s were still CRT, it was only in early 2010s that flat-screen TVs decisively overtook CRT. Major manufacturers announced the discontinuation of CRT, Digital Light Processing (DLP), plasma, and even fluorescent-backlit LCDs by the mid-2010s. LEDs are being gradually replaced by OLEDs. Also, major manufacturers have started increasingly producing smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s.[better source needed] (Full article...)

Al Jean, exec producer for more Treehouse of Horror episodes than any other EP
The Simpsons Treehouse of Horror episodes, also known as The Simpsons Halloween episodes, are a series of episodes in the animated television series The Simpsons. They are Halloween specials, each consisting of three separate, self-contained segments. These segments usually involve the Simpson family in some horror, science fiction, or supernatural setting. Considered non-canon, they always take place outside the normal continuity of the show and completely abandon any pretense of being realistic. The first Treehouse of Horror episode aired on October 25, 1990 as part of the second season and was inspired by EC Comics horror tales. As of 2007, there are 18 Treehouse of Horror episodes, with one airing every year. The episodes are known for being far more violent and much darker than an average Simpsons episode. Episodes contain several trademarks, including the alien characters Kang and Kodos, "scary names" in the credits, a special version of the opening sequence, and parodies of horror and science fiction films. The show's staff regard the Treehouse of Horror as being particularly difficult to produce as the scripts often go through many rewrites, and the animators typically have to design new characters and backgrounds.

Digital television (DTV) is a telecommunication system for broadcasting and receiving moving pictures and sound by means of digital signals, in contrast to analog signals used by analog (traditional) TV. DTV uses digital modulation data, which is digitally compressed and requires decoding by a specially designed television set, or a standard receiver with a set-top box, or a PC fitted with a television card.

His career progressed with starring roles in the thriller Zodiac (2007), the romantic comedy Love & Other Drugs (2010), and the science fiction film Source Code (2011).
