When it comes to Reality programmes, television companies generally sell more formats worldwide rather than individual shows. These include [Insert Country Here] Idol and Antiques Roadshow (originally British), Big Brother (originally Dutch), Dragon's Den (originally Japanese) etc. Reality shows, even those that give away vast prizes, are still cheaper to produce than a traditional program with paid actors, writers, elaborate costumes and sets. Especially if they can make their money back through phone-in voting and/or competitions.

One of the consistently popular reality shows both sides of the Atlantic are cooking shows. These range from small restaurant or total amateurs competing to impress world renowned chefs, to programmes following well-established television chefs, including some made in America featuring British chefs.

Big Brother (2000+)

Extraordinarily popular across the world, this programme featured a group of people who "volunteered" to spend a number of months together in a house while their every move is videotaped, as benefiting the title. People at home were given the chance to 'vote people out' until the winner left at the end gets the cash prize.

originally conceived in the Netherlands, it was adapted worldwide, including British, American and Australian adaptations. Throughout all of them the basic formula remains the same.

Big Brother US (2000+)

A group of strangers are locked together in a house. They must each chose a bed in one of the dormitory room, divide the chores such as cooking and cleaning, decide on what food items are to be purchased and compete in contests that can win rewards for the house. Every week each contestant goes into a soundproof room to make comments about the others. At the end of the episode you could vote for your favourite, whoever got the fewest votes was expelled from the house before the next filming, which was shown after the introduction of the following episode. All the cameras were hidden in the walls.

The Antiques Roadshow

This is a series that has been broadcast since 1979, featuring experts discussing possessions brought in by members of the public. An episode will typically take place in the grounds of a different stately home each week, and is broadcast all around the country. Among the unusual objects are valuable antiques, family heirlooms and things that turn out to be worth very little. Despite this, many of the objects with little monetary value have fascinating stories behind them.

Since 1997 there has been an American version of Antiques Roadshow, in which a group of expert appraisers travel from city to city, rented a large hall and invited everyone to have their treasures and junk evaluated for free. Like the original series, while the occasional valuable item is discovered, most of the heirlooms are interesting, but basically worthless.

Pawn Stars (2009)

A very similar programme is Pawn Stars, in which people bring in items hoping to either sell them, or use them to secure a loan. The shop is located in the gambling Mecca of Los Vegas, Nevada - so many customers are sure the can win big with a few more dollars. A British version, Pawn Stars UK, started in 2013.

Supernanny 2004-2012

A television series in which Jo Frost, a professional nanny and childcare author, visits parents struggling with tantruming toddlers and naughty children. By teaching the parents how to spend quality time with their children and also how to put them on the naughty step when needed, a more relaxed and beneficial home environment for both children and parents is created by the end of the episode.

An American spin-off entitled Supernanny USA was made in 2005. This had painful British stereotypes, depicting Jo Frost in Mary Poppins clothing and driving around in a London cab. It also had blaring background music, bullying viewers into feeling emotional at key points in the programme. Between 2011-2013 another American version, called America's Supernanny, was made with Deborah Tillman replacing Jo Frost.

Top Gear

The British version of the ultimate car show launched in 1978 and has been hosted by Angela Rippon, Noel Edmonds and Kate Humble. It is since the show has been hosted by the trilogy of James May, Richard Hammond and constantly controversial Jeremy Clarkson, as well as the mysterious tame racing driver known only as 'the Stig', that it has become internationally successful and according to the Guinness Book of Records, is the most-watched factual series - in the world. Moving away from reviewing cars and keeping motorists informed, the show now features celebrities racing cars around an aerodrome and motorised adventures in the world's most hostile environments, including the Arctic, the Sahara and Argentina. Special programmes have been dedicated to James Bond Cars while many of the specially adapted cars from the challenges themselves are on display at the National Motor Museum at Beaulieu Abbey.

An American version which is very similar to the UK original but with different hosts has been made.

Ground Force (1997-2005)

This was a television gardening programme hosted by Alan Titchmarsh, the famously braless, water-feature obsessed Charlie Dimmock and builder Tommy Walsh. This programme was popular enough to be promoted to a BBC1 slot after the first series, attracting over 12 million viewers at its peak. The programme is often credited with popularising decking and water features in British gardens. After the show proved popular on BBC America, in 2003 Walsh and Dimmock and Will Shanahan and Kirsty King hosted an American version, Ground Force America.

Changing Rooms (1996-2004) / Trading Spaces (2000-2008)

In the original British series starring Carol Smillie and starring Laurence Llewelyn-Bowen, two friends or couples would usually swap and redecorate the others' house, only to have an unveiling at the end of the programme. The American version was called Trading Spaces. Again, two families switch houses for a week to remodel a certain room on a limited budget. When the families return home they are asked if they love or hate the changes. This was regularly presented by Paige Davis.

Survivor

An example of a reality show that was more popular outside its home country is Survivor. The idea behind the series involves a group of people stranded on a deserted island with little food or supplies and trying to survive. The idea was developed in Britain and pitched to the BBC by independent production company Planet 24, but the BBC made a documentary series entitled Castaway 2000 instead. Planet 24 pitched their programme to television studios all around the world, and it became particularly popular in America, launching in 2000 and still being shown at time of writing. In the UK Channel 4 made two series in 2001-2, but it had little impact.

Wife Swap

Originally a Channel 4 programme broadcast between 2003-2009, the programme involves two couples. In each couple, the 'wife'¹ leaves her home and partner to stay for a two week period with the 'husband' of the other relationship and try to live their life style. The cameras record what happens and interview all concerned to see whether or not this experience will later influence their lives.

An American series was broadcast on ABC in 2004-2010, although it also influenced a similar programme broadcast on FOX entitled Trading Spouses, which was more family orientated. In this one of the parents, usually the wife would spend time living with the other's family. At the end each family was awarded a large sum of money that the visiting spouse would allocate as they saw fit. Many times a child would be given a musical instrument or tuition for special classes. Sometimes the family might be given a vacation, swimming pool or a second car.
