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.

Who created Compact Disc prototypes in the 1970s?
Answer: Philips and Sony

Traditional architecture is distinctive and include the Manueline, also known as Portuguese late Gothic, a sumptuous, composite Portuguese style of architectural ornamentation of the first decades of the 16th century. A 20th-century interpretation of traditional architecture, Soft Portuguese style, appears extensively in major cities, especially Lisbon. Modern Portugal has given the world renowned architects like Eduardo Souto de Moura, Álvaro Siza Vieira (both Pritzker Prize winners) and Gonçalo Byrne. In Portugal Tomás Taveira is also noteworthy, particularly for stadium design.

What is the Manueline style?
Answer: a sumptuous, composite Portuguese style of architectural ornamentation of the first decades of the 16th century

Since it was quite easy to stack interconnections (wires) inside the embedding matrix, the approach allowed designers to forget completely about the routing of wires (usually a time-consuming operation of PCB design): Anywhere the designer needs a connection, the machine will draw a wire in straight line from one location/pin to another. This led to very short design times (no complex algorithms to use even for high density designs) as well as reduced crosstalk (which is worse when wires run parallel to each other—which almost never happens in Multiwire), though the cost is too high to compete with cheaper PCB technologies when large quantities are needed.

Along with quick design times, what problem does Multiwire cut down on?
Answer:
crosstalk
