What was invented when? Ten technologies and their release dates


Presumably your apocalypse is going to render obsolete most if not all technology, but you still don't want your 80s teen protagonist texting her friends about the zombies at the post-prom party; she'd be on the telephone calling, not texting.


So before you bestow or remove tech from your characters, make sure your timeline of inventions lines up. Below is a list of ten technological inventions and their release dates.

When you think you're ready for an editor and/or proofreader for your post-apocalyptic novel (congratulations!), I'd be honored to read your work. My #1 goal as a freelance editor is to make your words flow so seamlessly your readers won't be able to put your book down!
