The origin of branding can be traced to ancient times, when specialists often put individual trademarks on hand-crafted goods. The branding of farm animals in Egypt in 2700 BC to avoid theft may be considered the earliest form of branding, as in its literal sense. As somewhat more than half of companies older than 200 years old are in Japan, (see: List of oldest companies), many Japanese businesses’ “mon” or seal is an East Asian form of brand or trademark. In the West, Staffelter Hof dates to 862 or earlier and still produces wine under its name today. By 1266, English bakers were required by law to put a specific symbol on each product they sold. Branding became more widely used in the 19th century, through the industrial revolution and the development of new professional fields like marketing, manufacturing and business management. Branding is a way of differentiating product from mere commodities, and therefore usage of branding expanded with each advance in transportation, communication, and trade. The modern discipline of brand management is considered to have been started by a famous memo at Procter & Gamble.
