Television (TV) is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports.

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 flat-panel, mainly LEDs. Major manufacturers announced the discontinuation of CRT, Digital Light Processing (DLP), plasma, and even fluorescent-backlit LCDs by the mid-2010s. In the near future, LEDs are expected to be gradually replaced by OLEDs. Also, major manufacturers have announced that they will increasingly produce 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. (Full article...)

In 1969, the children's television show Sesame Street premiered on the National Educational Television network (later succeeded by PBS) in the United States. Unlike earlier children's programming, the show's producers used research and over 1,000 studies and experiments to create the show and test its impact on its young viewers' learning. By the end of the program's first season, Children's Television Workshop (CTW), the organization founded to oversee Sesame Street production, had developed what came to be called "the CTW model": a system of planning, production, and evaluation that combined the expertise of researchers and early childhood educators with that of the program's writers, producers, and directors.

CTW conducted research in two ways: in-house formative research that informed and improved production, and independent summative evaluations conducted by the Educational Testing Service (ETS) during the show's first two seasons to measure the program's educational effectiveness. CTW researchers invented tools to measure young viewers' attention to the program. Based on these findings, the researchers compiled a body of data and the producers changed the show accordingly.

Publicity still, c.1962

Pierino Ronald "Perry" Como (/ˈkm/; May 18, 1912 – May 12, 2001) was an American singer, actor, and television personality. During a career spanning more than half a century, he recorded exclusively for RCA Victor for 44 years, from 1943 until 1987.

"Mr. C.", as he was nicknamed, reportedly sold 100 million records worldwide and pioneered a weekly musical variety television show. His weekly television shows and seasonal specials were broadcast throughout the world. He recorded primarily vocal pop and was renowned for recordings in the intimate, easy-listening genre pioneered by multimedia star Bing Crosby. In the official RCA Records Billboard magazine memorial, his life was summed up in these few words: "50 years of music and a life well lived. An example to all." (Full article...)
