"Antiques Roadshow" features some of Britain's leading antiques and fine arts specialists travelling to venues across the UK to offer free advice and valuations to visitors who bring along their family heirlooms and household treasures for inspection. The series began on BBC One in 1979 and has become a regular Sunday-evening fixture for millions of people. The show has also made celebrities of its experts, including Arthur Negus, Eric Knowles, Tim Wonnacott and Henry Sandon. Presenting duties have been handled chronologically by Bruce Parker, Angela Rippon, Arthur Negus, Hugh Scully, Michael Aspel and Fiona Bruce. Some of the incredible finds over the years have included a Lalique piece that was bought for £1 and was actually worth a five-figure sum and some Art Deco jewellery that earned its oblivious owner a small fortune. An original 1990s maquette of the Angel of the North sculpture by Antony Gormley, owned by Gateshead Council, was valued at £1million by Philip Mould. On the flipside, a man had his dreams of riches shattered when glassware he had spent more than £1,000 on was a worthless empty olive oil bottle that could have been purchased in Tesco in 2008. There have been a number of spin-off series, including "20th Century Roadshow", "Antiques Roadshow Gems" and "Priceless Antiques Roadshow", and the original series has visited a number of places outside Britain, including Canada and Australia. There are also a number of international versions of the series, including the American incarnation which is aired on PBS.
