Weet-Bix postcardA company called Grain Products Limited added small amounts of sugar and malt to flaked cereal biscuits and launched Weet-Bix in competition to the popular Granose. The company and the brand were acquired by Sanitarium in 1928. Weet-Bix  has been the best selling breakfast cereal in Australia for more than 35 years. A detailed history of the development of Weet-Bix, by a descendent of one of the founders, can be found here.
