Though women were protected by late Sumerian law and were able to achieve a higher status in Sumer than in other contemporary civilizations, the culture was male-dominated. The Code of Ur-Nammu, the oldest such codification yet discovered, dating to the Ur-III "Sumerian Renaissance", reveals a glimpse at societal structure in late Sumerian law. Beneath the lu-gal ("great man" or king), all members of society belonged to one of two basic strata: The "lu" or free person, and the slave (male, arad; female geme). The son of a lu was called a dumu-nita until he married. A woman (munus) went from being a daughter (dumu-mi), to a wife (dam), then if she outlived her husband, a widow (numasu) and she could then remarry.

In the 1990s, marked by the liberalization of language development and mother tongue movement in Taiwan, Taiwanese Hokkien had undergone a fast pace in its development. In 1993, Taiwan became the first region in the world to implement the teaching of Taiwanese Hokkien in Taiwanese schools. In 2001, the local Taiwanese language program was further extended to all schools in Taiwan, and Taiwanese Hokkien became one of the compulsory local Taiwanese languages to be learned in schools. The mother tongue movement in Taiwan even influenced Xiamen (Amoy) to the point that in 2010, Xiamen also began to implement the teaching of Hokkien dialect in its schools. In 2007, the Ministry of Education in Taiwan also completed the standardization of Chinese characters used for writing Hokkien and developed Tai-lo as the standard Hokkien pronunciation and romanization guide. A number of universities in Taiwan also offer Hokkien degree courses for training Hokkien-fluent talents to work for the Hokkien media industry and education. Taiwan also has its own Hokkien literary and cultural circles whereby Hokkien poets and writers compose poetry or literature in Hokkien on a regular basis.
When did Taiwanese Hokkien have a fast change in development?

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?
