Here is a question about this article: The Compact Disc is an evolution of LaserDisc technology, where a focused laser beam is used that enables the high information density required for high-quality digital audio signals. Prototypes were developed by Philips and Sony independently in the late 1970s. In 1979, Sony and Philips set up a joint task force of engineers to design a new digital audio disc. After a year of experimentation and discussion, the Red Book CD-DA standard was published in 1980. After their commercial release in 1982, compact discs and their players were extremely popular. Despite costing up to $1,000, over 400,000 CD players were sold in the United States between 1983 and 1984. The success of the compact disc has been credited to the cooperation between Philips and Sony, who came together to agree upon and develop compatible hardware. The unified design of the compact disc allowed consumers to purchase any disc or player from any company, and allowed the CD to dominate the at-home music market unchallenged.
What is the answer to this question: To what does the compact disc owe its prosperity?

So... cooperation between Philips and Sony


Here is a question about this article: Few large stone buildings were constructed between the Constantinian basilicas of the 4th century and the 8th century, although many smaller ones were built during the 6th and 7th centuries. By the beginning of the 8th century, the Carolingian Empire revived the basilica form of architecture. One feature of the basilica is the use of a transept, or the "arms" of a cross-shaped building that are perpendicular to the long nave. Other new features of religious architecture include the crossing tower and a monumental entrance to the church, usually at the west end of the building.
What is the answer to this question: When were the Constantinian basilicas built?

So... 4th century


Here is a question about this article: In 2000, TCM started the annual Young Composers Film Competition, inviting aspiring composers to participate in a judged competition that offers the winner of each year's competition the opportunity to score a restored, feature-length silent film as a grand prize, mentored by a well-known composer, with the new work subsequently premiering on the network. As of 2006, films that have been rescored include the 1921 Rudolph Valentino film Camille, two Lon Chaney films: 1921's The Ace of Hearts and 1928's Laugh, Clown, Laugh, and Greta Garbo's 1926 film The Temptress.
