There are different types of chocolate such as black, brown, and white that are commonly found in chocolate bars and ice cream. Chocolate has been consumed for over 2000 years and was originally produced just for eating. In 1847, Fry & Sons developed the first solid chocolate bar for snacking, making chocolate bars popular for happiness and socializing in the 18th century at "chocolate houses." Cocoa was also very important in Aztec culture, and chocolate can be made into drinks as well as gifts for Valentine's Day.

The document outlines the history of sound recording technology from 1877 to 2010, including key inventions like the phonograph in 1877, tape recorders in the 1920s, cassette tapes and compact discs in the 1960s and 1980s, mp3s and digital music in the late 1980s and 2000s.
