The core group of generic top-level domains consists of the com, info, net, and org domains. In addition, the domains biz, name, and pro are also considered generic; however, these are designated as restricted, because registrations within them require proof of eligibility within the guidelines set for each.
Historically, the group of generic top-level domains included domains, created in the early development of the domain name system, that are now sponsored by designated agencies or organizations and are restricted to specific types of registrants. Thus, domains edu, gov, int, and mil are now considered sponsored top-level domains, much like the themed top-level domains (e.g., jobs). The entire group of domains that do not have a geographic or country designation (see country-code top-level domain) is still often referred to by the term generic TLDs.
"Dance (Disco Heat)" is the title of a 1978 single by Americandisco singer Sylvester James, who performed using just his first name, Sylvester. The song became Sylvester's first Top 40 hit in the US, where it peaked at #19 on the Billboard Hot 100 chart in the fall of 1978; it also reached #29 on the UK Singles Chart. The song appears on his 1978 album, Step II.
A 12" single was released in 1978, with "Dance (Disco Heat)" as the A-side and "You Make Me Feel (Mighty Real)" as the B-side, and these two extended dance mixes proved to be very popular in the dance clubs at the time. The two songs held down the top spot on the BillboardDance/Disco chart for six weeks in August and September of that year and helped to establish Sylvester's career as a noted disco and dance music performer, both in the U.S. and abroad.
The Instructor began publication in 1930, when the Sunday School ceased publication of The Juvenile Instructor, its official publication since 1901. Like its predecessor, The Instructor was targeted primarily at the LDS Church's youth and young adult membership. The first editor of the periodical was George D. Pyper, a member of the general superintendency of the Deseret Sunday School Union.
