There’s a first time for everything, as the saying goes. It might feel like we’ve been sending email attachments forever, but actually the first one happened less than 20 years ago. AOL instant messaging, the beloved and one-time ubiquitous chat interface, only got started in 1993 when a future AOL executive messaged his wife: “Don’t be scared … it is me.”
Quartz dug up these and other technology “firsts” that paved the way for modern life as we know it. The first mobile phone call, the first website, the first tweet. Enjoy.
