Mobile (cell) phones have significantly evolved….at least size-wise….and feature wise.
The early phones were just phones….large and bulky. The latest are lightweight and mini computers….with crystal clear screens….and internet access. Though from the graphic they appear to reverting back to their original size!
From a business/organizational aspect….business can change dramatically in a 25 year period. Of course some don’t and that also counts towards their longevity.
Regardless, the key point is be ready for change and adapt to change as the market evolves….which it evidently will.
