	food spread extracted from yeast cells 
	The story of Vegemite is a tale of technological innovation and never-say-die promotion. 
 
In 1922 Fred Walker Foods hired Percy Callister to develop a useful food from vitamin-rich used yeast being dumped by breweries. Using enzymes to split open the yeast cells, he extracted the contents and blended them with vegetables and salt into a sticky black paste with a sharp taste. Vegemite hit the market in 1923 and promptly failed to sell.  
 
So in 1928 the company renamed its spread Parwill to compete against the top-selling British import, Marmite (get it? - 'if Marmite then Parwill') but Parwill flopped too.  
 
Walker Foods tried the Vegemite name again and gave it away with Walker cheese products and a couple of cars as prizes before Australians finally fell for it.  
 
In 1939 Vegemite was officially endorsed by the British Medical Association as a source of Vitamin B and was included in Australian Army rations during World War II. Buyers were now assured of the nutritional value of Vegemite, which has been a market leader ever since.
