1978 TWIX commercial
Twix is a candy bar made by Mars, Inc., consisting of a biscuit finger, topped with caramel and coated in milk chocolate. Being somewhat smaller in width than other confectionery bars, Twix bars are typically packaged in pairs. Twix was first produced in the UK in 1967, and introduced in the United States in 1979.
Twix was called Raider in Austria, Belgium, Denmark, Finland, France, Germany, Greece, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Spain, Sweden, and Switzerland for many years before its name was changed in 1991 (2000 in Finland, Denmark, Norway, Sweden and Turkey) to match the international brand name. In North America Twix is produced in Cleveland, Tennessee.
