Monster Beverage Corporation is an American beverage company that manufactures energy drinks including Monster Energy, Relentless and Burn. The company was originally founded as Hansen's in 1935 in Southern California, originally selling juice products. 

In the 1930s, Hubert Hansen and his three sons began selling juice to film studios and retailers in Southern California under the Hansen's name. In the 1970s, Tim Hansen (the grandson of Hubert) developed and marketed a variety of sodas and juices, also under the Hansen's label. 

The company became Hansen's Juices, and later The Fresh Juice Company of California. The plant that was opened in Los Angeles in 1946 was used until operations were moved to a new plant in Azusa, California in 1993.

The company filed for bankruptcy in 1988, and was acquired by the California CoPackers Corporation and renamed Hansen Natural Company. In 1998, the company moved from Anaheim, California to Corona, California. 

On January 5, 2012, shareholders agreed to change the name of the company from Hansen's Natural to Monster Beverage Corporation, under the new ticker MNST. Shareholders also approved an increase in the number of authorized shares of common stock to 240,000,000 shares from 120,000,000 shares.

As of May 2012, Monster held nearly 35% of the $31.9 billion US energy drink market. 

The company renamed itself as Monster Beverage in 2012, and then sold their Hansen's juices and sodas and their other non-energy drink brands to The Coca-Cola Company in 2015.
