Like many modern families, the Ashby Hawkins home is stuffed full of tablets, computers, phones, and gadgets to distract them in their spare time. But for one summer they agreed to give up all their 21st century technology and travel back in time, to experience the radical transformation of our leisure time since 1950.

The family's own home becomes their time machine as they are transported back to a different decade each week. Guided by presenters Giles Coren and social historian Polly Russell, the family's entire experience is underpinned by The Family Expenditure Survey, a government study which ran from the 50s right through to 1999. The survey's detailed spending records give us the best possible clue as to what families were doing with their leisure time across the five decades.
