We take it for granted today.
A blue wire with a clear plug. It's the most obvious description of Ethernet, but Ethernet itself is so much more. We may not think of it every day, but the simple act of getting information from one of millions of locations worldwide is a fabulous feat of engineering. Ethernet was dreamed up 40 years ago, and back then no one would have guessed that it would circle the world and power the greatest learning revolution in history.
Enough waxing poetic. There's an article over at the Broadcom blog
that does a much better job. Broadcom is one of those companies you never hear about, but their stuff is everywhere. They make the chips that power your DVR, the wireless chip for your computer, and most of the communications chips for your phone. They power your router, too.
If anyone knows about Ethernet, it's Broadcom... so check out their story!
