The digital data on a CD begins at the center of the disc and proceeds toward the edge, which allows adaptation to the different size formats available. Standard CDs are available in two sizes. By far, the most common is 120 millimetres (4.7 in) in diameter, with a 74- or 80-minute audio capacity and a 650 or 700 MiB (737,280,000-byte) data capacity. This capacity was reportedly specified by Sony executive Norio Ohga in May 1980 so as to be able to contain the entirety of the London Philharmonic Orchestra's recording of Beethoven's Ninth Symphony on one disc. This is a myth according to Kees Immink, as the code format had not yet been decided in May 1980. The adoption of EFM one month later would have allowed a playing time of 97 minutes for 120 mm diameter or 74 minutes for a disc as small as 100 mm. The 120 mm diameter has been adopted by subsequent formats, including Super Audio CD, DVD, HD DVD, and Blu-ray Disc. Eighty-millimeter discs ("Mini CDs") were originally designed for CD singles and can hold up to 24 minutes of music or 210 MiB of data but never became popular.[citation needed] Today, nearly every single is released on a 120 mm CD, called a Maxi single.[citation needed]

American Idol has traditionally released studio recordings of contestants' performances as well as the winner's coronation single for sale. For the first five seasons, the recordings were released as a compilation album at the end of the season. All five of these albums reached the top ten in Billboard 200 which made then American Idol the most successful soundtrack franchise of any motion picture or television program. Starting late in season five, individual performances were released during the season as digital downloads, initially from the American Idol official website only. In season seven the live performances and studio recordings were made available during the season from iTunes when it joined as a sponsor. In Season ten the weekly studio recordings were also released as compilation digital album straight after performance night.
What company has released studio recordings from American Idol since season seven?
iTunes

The secondary and high school education system in Swaziland is a five-year programme divided into three years junior secondary and two years senior secondary. There is an external public examination (Junior Certificate) at the end of the junior secondary that learners have to pass to progress to the senior secondary level. The Examination Council of Swaziland (ECOS) administers this examination. At the end of the senior secondary level, learners sit for a public examination, the Swaziland General Certificate of Secondary Education (SGCSE) and International General Certificate of Secondary Education (IGCSE) which is accredited by the Cambridge International Examination (CIE). A few schools offer the Advanced Studies (AS) programme in their curriculum.
