It’s not a secret, that some popular brands made their logos perfect not the first time, but after recreation they became one of the best examples for others.
Exactly such situation happened with “7 up” company, which logotype a few years ago wasn’t such as we see it now. The first version looked like a “7” with wings, because the slogan of company was “7 up gives you wings”.
After the first logotype, it was redesigned twice and the popularity started growing up.
“7 up” changed not only the design of logo, but also a slogan, now it sounds like “Feels good to be you”. Professionalism of designers is seen in the new logotype, because everyone can recognise a red circle and a green number “7”, it means that rebranding was done successfully.
