The Hamdog was created in 2004 by Australian Mark Murray, who successfully acquired a US patent for his invention in 2009. In 2015 Murray appeared on the TV programme Shark Tank, the Australian equivalent of the UK’s Dragon’s Den in which would-be entrepreneurs pitch their ideas to potential investors. Despite being turned down for funding at that time, he continues to persevere with his business idea, attracting global publicity in 2016. Murray’s is not the only hamdog around however. In 2005 an astonishingly artery-clogging version was invented in the US which is deep fried and includes chips and a fried egg!
