Platinum

Platinum is a chemical element with symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, gray-white transition metal. Its name is derived from the Spanish term platina, which is literally translated into "little silver".

Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for 80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity.

Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it became investigated by scientists.

Music recording sales certification

Music recording sales certification is a system of certifying that a music recording has shipped or sold a certain number of copies. The threshold quantity varies by type (such as album, single, music video) and by nation or territory (see List of music recording certifications).

Almost all countries follow variations of the RIAA certification categories, which are named after precious materials.

The number of sales or shipments required for these awards depends upon the population of the territory in which the recording is released. Typically, they are awarded only to international releases and are awarded individually for each country in which the album is sold. Different sales levels, some perhaps 10 times lower than others, may exist for different music media (for example: videos versus albums, singles, or downloads).

History

The original gold record awards were presented to artists by their own record companies to publicize their sales achievements. The first of these was awarded by RCA Victor to Glenn Miller in February 1942, celebrating the sale of 1.2 million copies of "Chattanooga Choo Choo". Another example of a company award is the gold record awarded to Elvis Presley in 1956 for one million units sold of his single "Don't Be Cruel". The first gold record for an LP was awarded by RCA Victor to Harry Belafonte in 1957 for the album Calypso (1956), the first album to sell over 1,000,000 copies in RCA's reckoning.

Bonkers!

Bonkers! was an ATV variety show, distributed by ITC Entertainment in the United States for syndication during the 1978-79 television season, and later airing in 1979 in the United Kingdom. Made at ATV's Elstree studios near London.

Starring Bob Monkhouse and the Hudson Brothers - Bill, Brett and Mark - the show featured sketches, guest stars and musical numbers from the chorus dancers known as The Bonkerettes. Whilst not a big hit for ATV, it gained a cult audience in the United States where it was compared to Saturday Night Live.

After four episodes the show was curtailed in the UK by the 13-week-long ITV strike of 1979 and did not reappear when the network restarted broadcasts; however, production for syndication continued and 24 episodes in total were made.

Bonkers! (game)

Bonkers! (also known as This Game is Bonkers!) was a race-style board game designed by Paul J. Gruen and produced by Parker Brothers and later by Milton Bradley. The object was to be the first player to score 12 points by adding instruction cards to the empty spaces in an attempt to move to several scoring stations. The game's slogan (for both versions) was "It's Never the Same Game Twice!"

Setup

Each game of Bonkers! came with the following:

List of The Price Is Right pricing games

Pricing games are featured on the current version of the American game show The Price Is Right. The contestant from Contestants' Row who bids closest to the price of a prize without going over wins the prize and has the chance to win additional prizes or cash in an onstage game. After the pricing game ends, a new contestant is selected for Contestants' Row and the process is repeated. Six pricing games are played on each hour-long episode. Prior to expanding to one hour in length, three games per episode were played during the half-hour format. With the exception of a single game from early in the show's history, only one contestant at a time is involved in a pricing game.

A total of 108 pricing games have been played on the show, 75 of which are in the current rotation. On a typical hour-long episode, two games—one in each half of the show—will be played for a car, at most one game will be played for a cash prize and the other games will offer merchandise or trips. Usually, one of the six games will involve grocery products, while another will involve smaller prizes that can be used to win a larger prize package.
