History of modern Software (Discussion)

[Nightwalker83]

It is interesting that the above site says this:

University students in the 1970's bought blank cards a linear foot at a time from the university bookstore. Each card could hold only 1 program statement. To submit your program to the mainframe, you placed your stack of cards in the hopper of a card reader. Your program would be run whenever the computer made it that far. You often submitted your deck and then went to dinner or to bed and came back later hoping to see a successful printout showing your results. Obviously, a program run in batch mode could not be interactive.

Do the modern computer/software working in the same way? How would they have created the first software package like what we are used to today?

Edit:

I found so more useful link which explain part of what I am wanting to know.
