Video

Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media.

Video systems vary greatly in the resolution of the display, how they are refreshed, and the rate of refreshed, and 3D video systems exist. They can also be carried on a variety of media, including radio broadcast, tapes, DVDs, computer files etc.

History

Video technology was first developed for Mechanical television systems, which were quickly replaced by cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing one of the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.

Video recorders were sold for $50,000 in 1956, and videotapes cost $300 per one-hour reel. However, prices gradually dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) decks and tapes to the public.

Global warming

Global warming and climate change are terms for the observed century-scale rise in the average temperature of the Earth's climate system and its related effects.

Multiple lines of scientific evidence show that the climate system is warming. Although the increase of near-surface atmospheric temperature is the measure of global warming often reported in the popular press, most of the additional energy stored in the climate system since 1970 has gone into ocean warming. The remainder has melted ice and warmed the continents and atmosphere. Many of the observed changes since the 1950s are unprecedented over decades to millennia.

Scientific understanding of global warming is increasing. The Intergovernmental Panel on Climate Change (IPCC) reported in 2014 that scientists were more than 95% certain that global warming is mostly being caused by increasing concentrations of greenhouse gases (GHG) and other human (anthropogenic) activities.Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to 1.7 °C (0.5 to 3.1 °F) for their lowest emissions scenario using stringent mitigation and 2.6 to 4.8 °C (4.7 to 8.6 °F) for their highest. These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing.

Got Talent

Got Talent is a talent show television format conceived and owned by Simon Cowell's SYCOtv company. A pilot was made in the United Kingdom in 2005, hosted by Paul O'Grady, but after O'Grady's split with ITV, the series was postponed, resulting in America's Got Talent – the first full series of the format.

It has spawned spin-offs in over 58 countries (as of April 2014), in what is now referred to as the Got Talent format, similar to that described by FremantleMedia of the Idol and The X Factor formats. In April 2014, the format was named the world's most successful reality TV format ever by the Guinness World Records.

History

Got Talent was an invention by The X Factor creator Simon Cowell, with comedian and talk show host Paul O'Grady producing a pilot for ITV in 2005 under the provisional title Paul O'Grady's Got Talent. O'Grady left the network after disputes with ITV, resulting in Cowell moving the concept to the United States while he and ITV searched for a new show host.

Due to these issues, the Got Talent franchise ended up debuting first as America's Got Talent on NBC on 21 June 2006, with judges David Hasselhoff, Brandy Norwood, and Piers Morgan. The show's original series was hosted by Regis Philbin. In 2016, the judging panel consisted of Howie Mandel, Heidi Klum, Melanie Brown, and Simon Cowell, and hosted by Nick Cannon, who has been the presenter since 2009. The grand prize on America's Got Talent is $1 million, and, since season 3, a chance to headline a show on the Las Vegas Strip. America's Got Talent proved extremely successful for NBC, pulling in high ratings in both total viewers and the younger 18-49 demographic. The show's initial success in America is credited with the eventual launch of the British series, and the overall global launch of the Got Talent franchise.
