Red Bull is an energy drink sold by Red Bull GmbH, an Austrian company created in 1987. Red Bull has the highest market share of any energy drink in the world, with 7.5 billion cans sold in a year (as of 2019).
Austrian entrepreneur Dietrich Mateschitz was inspired by an existing energy drink named Krating Daeng, which was first introduced and sold in Thailand by Chaleo Yoovidhya. He took this idea, modified the ingredients to suit the tastes of Westerners, and, in partnership with Chaleo, founded Red Bull GmbH in 1987 in Chakkapong, Thailand. In Thai, daeng means red, and a krating (known in English as a gaur or Indian bison) is a large species of wild bovine native to South Asia. Yoovidhya's heirs own majority stakes in both brands, and they both use the same red bull on yellow sun logo while continuing to market the separate drinks to the respective Thai and Western markets.
Budweiser (/ˈbʌdwaɪzər/) is an American-style pale lager produced by Anheuser-Busch, part of AB InBev.
Internationally, Budweiser may also refer to an unrelated pale lager beer, originating in České Budějovice, Czech Republic (historically Budweis) produced by the Budějovický Budvar brewery. The parallel existence of two separate brands with the same name has given rise to a series of trademark disputes. Usually, either Anheuser-Busch or Budějovický Budvar are granted the exclusive use of the Budweiser name in a given market. Anheuser-Busch commonly uses the Bud brand for its beer when Budweiser is not available.
