PAL-M is the TV system used in Brazil since February 19, 1972. At that time, Brazil was the first South American country to broadcast in colour. Colour TV broadcast began on September 1972 when the TV networks Globo, Tupi and Bandeirantes TV transmitted the Caxias do Sul Grape Festival. Transition from black and white to colour was not complete until 1977. Two years later, in 1979 colour broadcast nationwide in Brazil was commonplace

In Brazil, PAL is used in conjunction with the 525 line, 30 frame/s system M, using (very nearly) the NTSC colour subcarrier frequency. Almost all other countries using system M use NTSC.

NTSC being the "natural" choice for countries with monochrome standard M, the choice of a different colour system poses problems of incompatibility with available hardware and the need to develop new television sets and production hardware. Walter Bruch, inventor of PAL, explains Brazil's choice of PAL against these odds by an advertising campaign Telefunken and Philips carried out across South America in 1972, which included colour test broadcasts of popular shows (done with TV Globo) and technical demonstrations with executives of television stations.

Pig Destroyer is a grindcore band from Virginia, USA.

The band formed in 1997 with vocalist J. R. Hayes (Enemy Soil), guitarist Scott Hull (Agoraphobic Nosebleed, Japanese Torture Comedy Hour, ex-Anal Cunt), and drummer John Evans. Evans was later replaced by Brian Harvey. Sampler Blake Harrison joined prior to recording Phantom Limb.

In an interview, Scott Hull claims that they picked the band name on the criteria that it was insulting, yet somewhat more creative than the name of his last band, Anal Cunt. Deciding that "Cop Killer" or "Cop Destroyer" would be tactless, they eventually settled on "Pig Destroyer" ("pig" being a pejorative American slang term for the police). Derived from a non-musical source as extreme as the band's sound, Pig Destroyer's easily identifiable logo was created using the emblem from ANSWER Me! magazine as a template. However, the band has become less political in recent times.

Relapse Records signed the band and issued a split 7" with Isis on the label's Singles Series in July 2000. 38 Counts of Battery was a complete discography of Pig Destroyer releases up to the year 2000, which included split records with Gnob and influential screamo act Orchid, as well as their debut album, Explosions In Ward 6, and the demo that secured their record deal.
