How did kitkat company start?

Answer 1

The name is the simplest -- it was taken from the KitKat club, an 18th-century literary salon in Christopher Catling's (hence the "Kit Cat") pie-house in Shire Lane, England. However, since it was initially launched in London and the South East in September 1935 as 'Rowntree's Chocolate Crisp', and re-named two years later as KitKat Chocolate Crisp, it may have actually been named for later variations of the KitKat club.

Kit Kat bars don't actually have a single shape/size. They are half-finger sized Kit Kat Petit in Japan, have only three fingers in Arabia, and are giant -- twelve-finger family-size bars -- in Australia and France. There are also dozens of variations on the flavor, so that can't be answered either. See link below.

Answer 2

The Kit Kat was originally made in the south east of London (UK), at Rowntree Factory. It was invented in September 1935, as a four finger Kit Kat bar.
