Coke's Water Bomb

7.30pm, BBC2

There are few things more enjoyable than a large international conglomerate falling flat on its face. Especially as a result of trying to pull a fast one on the public. That's what happened in February this year when Coca-Cola launched its Dasani bottled water onto the UK market with a £7 million marketing budget.

The plan was that the "pure" water would be as big a success over here as it is in the States. But that hope went down the drain with the revelation that the UK Dasani was, in fact, tap water from Sidcup in Kent, which Coca-Cola was selling at 95p a bottle. After just five weeks, the brand was withdrawn. This Money Programme investigation looks at how such a major company could have got a new product so wrong.
