Like I know the transfer speeds are vastly different.

But I don't understand is why they are faster. And why couldn't they have implemented USB 3.0 when they released 1.0? Like what technical breakthrough was required to get transfer speeds that fast?

Was it

cost?
capacities of computer? like they couldn't read the data fast enough? Although USB is still well below hard drive transfer speeds
engineering breakthrough? They found some new material which could transfer at a faster rate? Was this in the cable itself? In the hardware?
