Grange Hill is the country's favourite children's television show lost to our screens.
A poll found that the drama, which tackled bullying, racism and drug abuse among teenagers, tops the list of tele programmes we admire from the past.
Whether it was the main character Peter 'Tucker' Jenkins' rebellious attitude or the hard-hitting plots is up for debate, but the show's last impact is beyond doubt.
Of 2,000 Britons chosen to take part in the survey by Perspectus Global, just under half say it was their favourite show, while more than 80 per cent think tele in their childhood outclasses today's options.
Running for 30 years, Grange Hill was instrumental in addressing substance abuse amongst youngsters delivering the campaign: 'Just Say No'.
The survey asked people over the age of 40 what other programmes, which cannot be watched on regular television anymore, they remember fondly.
Coming in after Grange Hill was the Flintstones. The pioneering cartoon depicted the lives of Fred and Wilma Flintstone in Bedrock.
Their witty exchanges made television history becoming the first animated show to make it onto prime-time TV.

More than a third rank Postman Pat as their favourite show from the past.
Set in Greendale the adventures of Pat and his cat Jess, were accompanied by one of the most remembered theme tunes of all children's TV history.
In fourth place came the zany classic The Magic Roundabout with its rich array of cookie characters like Dougal and Zebedee.
The popularity of these shows means that for nearly four in ten people asked they are actually their happiest childhood memories.
Maybe this is because just over 40 per cent of people believe TV programmes were more imaginative in the past.
And an overwhelmingly majority, 94 per cent, would rather their own children watch these classics than spending hours scrolling online.

The research found that one of the problems is the massive number of stations to choose from compared to the few that were available decades ago.
Other favourites mentioned include Danger Mouse, The Sooty Show, Bagpuss and Thomas the Tank Engine.
Harriet Scott founder of Perspectus Global said: 'It shaped a lot of our histories and means a lot to us. It is amazing how many people can still hum the theme tunes from most of these shows, despite not having seen them for decades.
'Whether or not quality remains as high is subjective, there are so many shows like Bluey which kids love nowadays and may well form the basis of a similar list in 60 years time!'
