The O'Brien family continued developing the Breville business for three generations, with Bill's son John O'Brien setting up the Breville Research and Development centre in the late 1960s. In 1974 it completed development of the toastie maker selling 400,000 units in its first year and making Breville a household name in Australia. In 1977, Breville launched Australia's first food processor, the Breville Kitchen Wizz. Other firsts include the world's first high wall heating electric wok, the adjustable height sandwich press, the active arm citrus press and in 2010 the world's first juice extractor to juice whole fruit.
Today Breville trades in over 30 countries including China, Brazil, South Africa, Mexico, and Israel. Brevilles product development division is one of Australia's largest industrial design centres, and one of the largest worldwide in the small electrical appliance sector. Breville's R&D team has over 100 active patents and has been awarded more than 40 international design awards. Breville's Centre of Design Excellence is now located in Botany in Sydney.
