When the pilot of this new style of consumer series was broadcast in January this year, it was reviewed enthusiastically by The Times, who said it was "people power at the cutting edge... and entertaining with it".

Private Investigations draws on the style of the Bafta award-winning Video Diaries, giving ordinary people a camcorder so that they can make a film about something that makes them angry or just plain curious. And some of the campaigns in the pilot programme scored notable results, including questions in the House of Commons about a company executive's alleged clash of interests and a policy review by one local council on dog muck in its parks.

Each programme comprises four films. Items in the first include a report by two women who live in a block of flats with no bathrooms as they track down the person responsible to try to get proper washing facilities installed, and a man who tries to overcome his fear of flying.
