In 1935 The Clamato Corporation of New York produced "clam and tomato juice in combination".
In 1957, McCormick & Company, Inc. applied for, and later acquired, the Clamato brand name for the seasoned blend of tomato juice and clam juice. 
Clamato was produced in its current form beginning in 1966 by the Duffy-Mott company in Hamlin, New York, by Francis Luskey, a chemist, and another employee who wanted to create a Manhattan clam chowder style cocktail by combining tomato juice and clam broth with spices. Its history extends further back, however, as a nearly identical drink was already present in a cookbook published a decade earlier. The employees named the new cocktail "Mott's Clamato" and secured the trademark for the new brand. The brand was owned by Cadbury-Schweppes after the company bought Mott's in 1982. As of 2008, it is owned by Keurig Dr Pepper after the business was spun off of Cadbury-Schweppes.
Clamato is used primarily as a drink mix for alcoholic beverages (an estimated 60% of sales in the US in 2008), and it is popular for this in both Canada and Mexico, but less so in the United States (outside of Canadian-American and Mexican-American communities). In Canada it is primarily used to make a cocktail called a Caesar.
Clamato is also added to beer in various beer cocktails, such as the michelada; the most basic is known as a "beer 'n clam" or a "Red Eye" in Western Canada, which adds Clamato to pale lagers. In 2001, Anheuser-Busch and Cadbury-Schweppes introduced a premixed version called the "Budweiser and Clamato Chelada" in the United States, which was criticized by American beer critics.
Beefamato is a similar beverage, but made from beef broth and tomato juice, with a touch of Worcestershire sauce. Beefamato is a popular ingredient in many cocktails, such as "Gramma's Bloody Mary".
