The G-string or thong is probably the earliest form of clothing known to man; having originated in the warmer climates of sub-Saharan Africa where clothing was first worn nearly 75,000 years ago. Many tribal peoples, such as some of the Khoisan people of southern Africa, wore thongs for many centuries. Much like the 2000-plus-year-old Japanese fundoshi, these early garments were made with the male genitalia in mind.Although developed for the male anatomy by primitive peoples, in the modern West thongs are more often worn by females. They first gained mainstream popularity as swimwear in South America, particularly in Brazil in the 1970s. In Brazil, where the buttocks ("bunda" in Portuguese) are especially admired and emphasized; it was originally a style of swimsuit whose rear area became so narrow that it would disappear between the wearer's buttocks.

The origin of the term "G-string" is obscure. The term is first attested in writings by Americans in the late 1800's regarding the loincloth of Philippine natives. The origin of the word "thong" is from the Old English thwong, a flexible leather cord.
commercialisation and attitudes Attitudes to wearing G-strings vary, as usual with revealing clothing. By the late 1980s, the design had made its way into most of the Western world, and G-string underwear became more and more popular through the 1990s. As of 2003, thong underwear is one of the fastest-selling styles among women and currently gaining popularity among men.[citation needed] One advantage attributed to the wearing of thong underwear is that no visible panty line can be seen even under a thin, light-colored or skin-tight garment, which makes for a more attractive appearance. Although the popularity of wearing thong underwear in America has taken off only in the last decade, in Eastern and Northern Europe it has been common for many more years, and is considered commonplace today.

Today, there are a number of intermediate styles between full rear coverage and a string rear. They include the rio, tanga, thong, string thong and microkini. A style that has a narrow band of fabric in the rear that just covers the cleft in the buttocks is often called a "Brazilian" rear, because it is often seen at Brazilian Samba carnivals.In recent years the hip hop and R&B music industry has also helped to promote the G-string, mostly under its American nomenclature of 'thong' by composing songs about it and featuring artists clad in them. Artists include Britney Spears, Christina Aguilera and Lil' Kim. One example of music that popularized this undergarment is the "Thong Song" by Sisq?, which was released in 2000. G-strings have become icons of pop culture, often with pop female artists wearing clothing that is revealing enough that their wearing of a thong is obvious, and thus the younger generation of American females following suit has increased the popularity of wearing thong underwear.

Male use of G-string underwear, in the West traditionally limited to the athlete's jockstrap and the dance belt, is currently increasing due to the popularization by male strippers and/or exotic dancers, e.g. Chippendales dancers. G-strings are very popular with male wrestlers like Hulk Hogan because they don't produce visible brief lines under their wrestling suits. Male use of G-strings as beachwear is not as popular in the U.S. as it is in other countries such as France.
As is the case with many icons of pop culture, G-string underwear is not without its own controversies. In 2002 American clothing retailer Abercrombie & Fitch, known for their racy catalogues, launched a line of G-string underwear marketed specifically at girls aged 13 to 16 years. Several consumer advocacy groups objected to marketing of the G-string, claiming they are too sexually suggestive.
In April 2002, G-string underwear was at the centre of a media uproar after a vice-principal (a woman) at Rancho Bernardo High School in southern California forced female students to lift their skirts before entering a school dance, in a so-called crackdown on G-string underwear.

In May 2003, the head teacher of a British primary school voiced her concern after learning that girl pupils as young as 10 were wearing thong underwear to school. This incident led to a media debate about the appropriateness of G-string underwear and the sexualization of children.
Many beachside municipalities in the United States have legislation forbidding G-string swimsuits in public, while others governments such as that of Virginia have attempted to pass laws forbidding the exposure of underwear. These actions are believed to have been prompted by both the deliberate and inadvertent exposure by young women of their G-string as well as a current trend at the time of men wearing their pants so low down that the pubis was exposed. Virginia's so-called "droopy-pants" bill failed to report in a state senate committee two days after having been passed by the state house.
