The mass hysteria began in 2007 when Apple introduced the first iPhone.
10 years on, the craziness to get a brand new iPhone as soon as it launches continues.
We go down memory lane before the unveiling of iPhone 8, iPhone 8 Plus and iPhone X.

The hysteria was the same across the pond in the United Kingdom 5 months later. Customers braved the November chills and stayed in queue overnight for it.

Enterprising dealers in some parts of the world made people wait in queue for the phone, but -- like this man -- realised that not all his minions were ready to part with the phone at the decided price.
