1936 The British Broadcasting Corporation (BBC) Debuts World's First Television Service

1936 The British Broadcasting Corporation (BBC) debuts the world's first television service with three hours of programming a day.

At 3pm on 2 November 1936 the BBC began the world's first regular hi-definition television service, from specially constructed studios at Alexandra Palace in North London. As part of this, two different technical systems were being tested on alternate weeks for six months: John Logie Baird's mechanical system producing pictures of 240 lines, and the EMI-Marconi electronic system, which produced images of 405 lines. On the toss of a coin, Baird's system inaugurated the service, followed by EMI-Marconi's. The latter was to prove the winning system.

The formal opening ceremony was followed by a Movietone newsreel and then a variety show, featuring Adele Dixon and the BBC Television Orchestra. A short documentary, Television Comes to London, revealed the preparations leading up to the launch. In all, the service was on the air for two hours on its first day.

BBC Director General John Reith did not like the new medium, and in later life said he never watched television. However, he was in a minority as television became the dominant medium of the twentieth century. The term hi-definition as used in 1936 was defined as a minimum of 240 lines, and was applied in contrast to Baird's earlier system which used only 30. Today, standard definition at 625 lines is being replaced by digital hi-definition, which offers picture resolution of 1080 lines.

The Simpsons - 1990

The Simpsons is an American animated sitcom created by Matt Groening. The series is a satirical depiction of a middle class American lifestyle epitomized by the Simpson family, which consists of Homer, Marge, Bart, Lisa, and Maggie. The show is set in the fictional town of Springfield and parodies American culture, society, television, and many aspects of the human condition.

The family was conceived by Groening shortly before a solicitation for a series of animated shorts with the producer James L. Brooks. Groening created a dysfunctional family and named the characters after members of his own family, substituting Bart for his own name. The shorts became a part of The Tracey Ullman Show on April 19, 1987. After a three-season run, the sketch was developed into a half-hour prime time show and was an early hit for Fox, becoming the network's first series to land in the Top 30 ratings in a season (1989–1990).

Since its debut on December 17, 1989, the show has broadcast 552 episodes and the 25th season began on September 30, 2013. The Simpsons is the longest-running American sitcom, the longest-running American animated program, and in 2009 it surpassed Gunsmoke as the longest-running American scripted primetime television series. The Simpsons Movie, a feature-length film, was released in theaters worldwide on July 26 and 27, 2007, and grossed over $527 million.

The Simpsons is widely considered to be one of the greatest television series of all time. Time magazine's December 31, 1999, issue named it the 20th century's best television series, and on January 14, 2000, the Simpson family was awarded a star on the Hollywood Walk of Fame. It has won dozens of awards since it debuted as a series, including 31 Primetime Emmy Awards, 30 Annie Awards and a Peabody Award. Homer's exclamatory catchphrase "D'oh!" has been adopted into the English language, while The Simpsons has influenced many adult-oriented animated sitcoms.

The Price is Right - 1956

The Price Is Right is an American game show hosted by Bill Cullen which aired on NBC from 1956 to 1963 and on ABC from 1963 to 1965 in both daytime and prime-time. Four contestants made successive bids on merchandise prizes with the goal of bidding closest to the actual retail price of the prize without going over.

Bill Cullen hosted both the daytime and nighttime versions of the show. For two seasons (1959–60 and 1960–1961). Cullen's easygoing personality was cited as a key part of the show's success. The show gained popularity during the years following the quiz show scandal, becoming the most-watched prime-time game show from 1959–1961.

The show was a precursor to the current and best-known version of the show, premiering in 1972 on CBS (as The New Price Is Right) and in syndication. Therefore, The Price Is Right as a whole is often said to have had the rare distinction of appearing on all three major networks (NBC, ABC and CBS).

As The World Turns - 1956

As the World Turns (often referred to as ATWT) is an American television soap opera that aired on CBS from April 2, 1956 to September 17, 2010. Irna Phillips created As the World Turns as a sister show to her other soap opera The Guiding Light. Running for 54 years, As the World Turns holds the second-longest continuous run of any daytime network soap opera in American history, surpassed only by Guiding Light. As the World Turns was produced in New York City for all of its time (its first 43 years in Manhattan and in Brooklyn from 2000 until 2010).

Set in the fictional town of Oakdale, Illinois, the show debuted on April 2, 1956,[at 1:30 pm EST. Prior to that date, all serials had been fifteen minutes in length. As the World Turns and The Edge of Night, which premiered on the same day at 4:30 pm EST, were the first two to be thirty minutes in length from their premiere. At first, viewers did not respond to the new half-hour serial, but ratings picked up in its second year, eventually reaching the top spot in the daytime Nielsen ratings by fall 1958. In 1959, the show started a streak of weekly ratings wins that would not be interrupted for over twelve years. The show switched to color on August 21, 1967, and expanded from a half-hour in length to one hour starting on December 1, 1975 when The Edge of Night moved to ABC. In the year-to-date ratings, As the World Turns was the most-watched daytime drama from 1958 until 1978, with ten million viewers tuning in each day. At its height, core actors such as Helen Wagner, Don MacLaughlin, Don Hastings, and Eileen Fulton became nationally known. Three of these actors – Wagner, Hastings, and Fulton – are also the three longest serving actors in the history of American soap operas.

The show passed its 10,000th episode on May 12, 1995, and celebrated its 50th anniversary on April 2, 2006. On September 18, 2009, As the World Turns became the last remaining Procter and Gamble produced soap opera after Guiding Light aired its final episode.

On December 8, 2009, CBS announced that it canceled As the World Turns because of low ratings. The show taped its final scenes on June 23, 2010, and with a dramatic storyline finale, its final episode aired on September 17, 2010. On October 18, 2010, CBS replaced As the World Turns with talk show The Talk.
