We sourced a basic GPS module for a student project in the late 2000s, it had an antenna the size of a charcoal briquette, drew a bunch of power, wasn't all that cheap, and took a while to lock on to satellites. I can only imagine how crappy and expensive an accelerometer would have been at that time. The smartphone revolution was a gamechanger for the price and availability of GPS receivers as well as accelerometer/gyro systems.
