I've been around long enough to remember the world BS.
In this case, BS refers to the era "before smartphones," although when it comes to 24/7 access to the internet and social media, I can forgive someone for thinking it's a reference to something else.
When the iPhone revolutionized communication, commerce, marketing and just about every other industry, there was a great deal of excitement for updates of every app, for the iPhone itself and for the introduction of new apps. It was like we were experiencing pure magic.
The technology was so new, every update brought mind-blowing new capabilities. Most everyone who'd become familiar with computers willingly consumed the smartphone society, and were willingly consumed by it. Social media turned smartphones into the most influential devices on the planet.
