How USB took over everything—from the clunky one-way Type-A to today’s reversible USB-C—told from our bar-stool friend after a couple drinks.
You ever notice how USB just kind of became the thing that runs everything in your life? One day we’re plugging in beige printers with cables thick enough to tow a car, and the next we’re charging laptops, phones, and toothbrushes off the same port. It’s wild. But it didn’t just happen — it’s been nearly three decades of engineers fighting physics, cost, and human frustration to make that little rectangle (and now that little oval) work right.
Let’s wind it back.
Back When Ports Were Chaos
The year’s 1995. Intel’s running the show, Microsoft’s figuring out Windows 95, and everyone’s losing their minds trying to make peripherals work. You’ve got serial ports for modems, PS/2 ports for mice, parallel for printers, and if you were really in the weeds, SCSI chains that looked like spaghetti wiring a photocopier to a toaster.
So Intel gets this idea — well, really Ajay Bhatt does — to make a single port that does it all. Universal Serial Bus. They bring in Microsoft, Compaq, IBM, DEC, NEC — basically every big nerd from the ’90s — and start hammering out a spec that could work for everything. Plug and play, power and data, and no dip-switches or IRQs.
And they did it. USB 1.0 dropped in 1996, 12 megabits per second, and it worked. Not fast, not fancy — but simple. Then, two years later, Apple launches the iMac G3 — translucent blue, looks like candy — and kills off all their legacy ports. Just two USB ports. Boom. Overnight, the world moves to USB because, well, if Apple did it, everyone else had to catch up.
That’s the funny part — Intel made it, Apple made it matter.
When Apple Went Off Script
Fast-forward a decade and Apple, being Apple, decides to go rogue. USB 2.0 was topping out at 480 megabits per second, which felt like dial-up in a broadband world. So Intel and Apple teamed up again and built Thunderbolt.
