Nick Jr, the number one rating commercial preschool TV channel from Nickelodeon UK, has announced that its 2008 Jump Up outdoor event, taking place at the National Bowl, Milton Keynes from 25-27 July, will be its biggest yet with 40% more attendees.

The fourth annual Jump Up will welcome 21,000 preschoolers and their parents, making it the UK's largest free annual children's event. Last year, the event saw 15,000 tickets snapped up within half an hour through Nick Jr's website (www.nickjr.co.uk).

The show creates a live version of the Nick Jr brand, inviting under fives to join in the fun and adventures with the channel’s best-loved shows, including Dora the Explorer, Peppa Pig, Go, Diego, Go!, LazyTown and The Backyardigans, with themed activity zones, play areas and a spectacular musical stage show featuring their favourite TV characters.

"Jump Up has seen phenomenal success over the last three years and we are delighted to welcome thousands more people to join in the fun this year,” says Steven Brabenec, director of consumer marketing at Nickelodeon UK. "Jump Up is the ultimate expression of Nick Jr's 'Join In' values, where preschool children and their parents can sing, dance and play with their favourite Nick Jr characters and have their best day ever."

Following last year's event in Manchester, Nick Jr's Jump Up 2008 has moved to the National Bowl, Milton Keynes. "This is the perfect venue for Jump Up – it is well located, has great access and parking and is within an hour of London and Birmingham,” says Ian Irving, sales and marketing director at Nick Jr's newly appointed brand experience agency, Sledge. "We are working with Nick Jr to make this year's event bigger and better than ever."
