When GSM was first launched in Europe a long long long time ago back in 19992 the GSM logo could quite often be seen in advertisements. It's gone a bit out of fashion in the past decade but every now and then I still stumble over it like in the image on the left I took in Bratislava. I've done a lot of research into the history of GSM but I could never find any information on the logo. Who designed it and what do the 4 dots you can see in the "M" of GSM signify. Who put them there? It's all a big mystery. If you know something about this, I'd be glad if you could share it in the comments below.
