Last week we brought you the first part of Revolutions: Ideas that Changed the World. The BBC series looks at six inventions that upturned and forever-changed civilisations’ ability to navigate the world. This week’s episode considers perhaps one of the most pertinent examples of this phenomenon. It’s the “device that defines our age” – the smartphone. The programme uses a truly relatable invention to illustrate engineering and technological advancement.

Once again, Revolutions charts the surprisingly long history of what is this time one of the most ubiquitous inventions of our time, the smartphone.

From fire signals to woefully delayed letters to Morse code, we learn about humans’ struggle to communicate long distance.

The many breakthroughs and brainwaves culminate in the explosion of connectivity we know and (almost) all use on a practically hourly basis.

What results is the conundrum we face and are tackling by the day: the ramifications of having near limitless communication and access to knowledge.

Beyond this, the programme looks to the future of how we’ll continue to streamline and integrate our interfaces and the possible endgame.
