Vegemite is a thick, dark brown Australian food spread made from leftover brewers' yeast extract with various vegetable and spice additives. It was developed by Cyril Callister in Melbourne, Victoria in 1922. The Vegemite brand was owned by Mondelez International until January 2017, when it was acquired by the Australian Bega Cheese group in a US$460,000,000 agreement for full Australian ownership after Bega would buy most of Mondelez International's Australia and New Zealand grocery and cheese business.
