You're exactly right about the analogy other than that timesharing was already going in the late 1960's. I know because I was there and used SBC and then a different IBM 370 service bureau to write and run interactive jobs that their in-house computing staff couldn't do in a timely fashion.
The company I worked for eventually bought an IBM 5100, the predecessor of the IBM PC, to do the same work in house, due to cost.
