In the old times, the information system would have acted very differently to how it exists today. There weren't computers to assist the company in how it operates, and it would have all been done by hand. An example of this is if you were purchasing a vehicle, there wouldn't have been a easy method of knowing what the vehicle is, and it was learnt by reading newspapers, and learning from others who have recently purchased the vehicles. Once you purchased the vehicle, all maintainence and servicing of the vehicle would have been done by visiting a mechanic who would tell you what the vehicle needs done, as nowadays you can search up on the internet how to upgrade your car, and keep it properly maintained.
