Episode 10

It's the final episode of this series of Dragons' Den, which has seen a record number of investments from the Dragons.

Hoping to follow in the footsteps of the likes of Kirsty Henshaw, Angela Newman, Chris Barnado and Richard Blakesley, Ian Taylor rides into the Den with his mobile video advertising hoarding on a bike. He wants to expand his Wakefield-based business into the rest of the country, but will the Dragons see nationwide potential in his idea?

One of the Den's youngest entrepreneurs, 20-year-old Jessica Ratcliffe, thinks she's found a way into the lucrative computer gaming market with her online marketplace for selling and swapping used games. Now she wants to persuade a Dragon that they need a piece of the action. Plus another young but very experienced entrepreneur has an accessory that solves a problem all parents of newborns will relate to - how and where to change your baby's nappy in a public environment. But will the multimillionaires recognise the issue and. more importantly, will they spot a money-making opportunity?

Also, there's a round-up of the highlights from the series.
