Alan Sugar was known on Dragon's Den's related British business television landscape as the founder of the Amstrad electronics company.
Alan Sugar founded Amstrad in 1968, and the company became associated with consumer electronics, home computers and satellite television equipment. His entrepreneurial career made him a prominent British business personality long before he became associated with The Apprentice.
A common mix-up is placing Sugar among the regular Dragon's Den investors. He was not a main-series Dragon on the British programme. This question tests the connection between the named entrepreneur and the company for which he is best known, rather than suggesting that he sat on the Dragon's Den panel.
Dragon's Den investors have included Peter Jones, Deborah Meaden and Theo Paphitis. Sugar's famous television role was instead as Lord Sugar in The Apprentice.
