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.
"Cape Feare" is the second episode of The Simpsons' fifth season, which premiered on the Fox network on October 7, 1993 after being held over from season four. The episode features Sideshow Bob trying to kill Bart Simpson after getting out of jail. It is a spoof of the 1962 film Cape Fear as well as its 1991 remake, but alludes to other horror films. The production crew found it difficult to stretch "Cape Feare" in order to fulfil the standard length of a half-hour episode, leading to the padding of several scenes for which some became memorable. "Cape Feare" was written by Jon Vitti and directed by Rich Moore and was the last episode that the original writing staff helped produce. Kelsey Grammer guest stars as Sideshow Bob. The episode is generally rated as one of the best of the entire series and the score received an Emmy Award nomination.
