Grange Hill closed its school gates forever 10 years ago but its memory lives on thanks to Generation GH who grew up with the children's show. On Grange Hill's 40th birthday, we celebrate 40 facts about the iconic series

It's more than 40 years since a cartoon sausage on a fork flew across our television screens and launched a whole new era of children's TV.

Grange Hill has just celebrated its 40th birthday, which means a full four decades have passed since the landmark BBC drama first aired at teatime and Generation Grange Hill was born.

Writer Phil Redmond, who devised the series which was set in a fictional north London school, hoped to create a gritty show that took an unflinching look at working class life and the issues faced by inner-city teenagers. And to an extent, he was successful.

Whether you remember the sausage from the opening credits, Zammo scrabbling for heroin in a toilet, being terrified of bully Imelda, Row-land Browning or their long-suffering teachers, there's no question that Grange Hill left an indelible mark on children's television. To celebrate the show's ruby anniversary, here are a whole host of gems about the show that had everyone just saying no.
