It has enlightened numerous generations about world issues and the environment we live in, and has managed to keep it interesting consistently. It's been through many generations television-wise as well, it was in black and white for 20 years before changing to colour in 1970.
The show itself has changed a lot since it started, in order to keep up with the children of that age. It's never out of date and is always in tune with what kids like, this is simply because they interact with young people so they know what is "in" and what's not for them, so they can make the programme as good as possible.
As well as entertaining, Blue Peter has been fantastic in the work it has done for charities, getting the viewers involved in their appeals- the latest one to help Childline which it has done by collecting old mobile phones. It's not just in a studio either, presenters are challenged to attempt daring activities such as sky diving and skiing. Each year, the team visit at least one foreign country, where they discover the cultures there and look into it's history.
To sum up, Blue Peter is thoroughly enjoyable as well as educational. It covers all kinds of topics- past, present and future. Without it our childhoods would have been a lot less interesting, with Blue Peter badges to be awarded and prizes to be won, as well as lives to be saved.
Thankyou Blue Peter!
