How have telecommunications and associated devices have evolved since the 1990s.

The telecommunications and associated services have seen a remarkable change and progress since the 1990's, so much so that the phones as the main instrument have changed to a degree that has been a thing of sci-fi movies.

Until the 1990's, the telecommunication was using static phones and wires that were connecting them to the network, and that was it, there was no other function. Than in the 1990's, the first mobile phones were invented, and the era of wireless communication started. The mobile phones, at the start, had the same function as the static phones, but they had huge advantage that you were able to carry them around with you wherever you go. As the time passed, the mobile phones were developing more and more, and games, calculators, and multiple other basic things were included on them. Than on the scene appeared the androids and the IPhones. They were not using buttons anymore, but instead everything was on touch. Numerous applications were included, excellent hard drives and software, large memory capacity, and the phones became literary a mini computers that can be used for pretty much everything, giving no signs whatsoever that until very recently their ancestors where static and had only one function.
