Before the microcomputer, a successful software program typically sold up to 1,000 units at $50,000–60,000 each. By the mid-1980s, personal computer software sold thousands of copies for $50–700 each. Companies like Microsoft, MicroPro, and Lotus Development had tens of millions of dollars in annual sales. [37]
The evolution of software engineering is notable in a number of areas: Emergence as a profession: By the early 1980s software engineering had already emerged as a bona fide profession, [2] to stand beside computer science and traditional engineering. [citation needed]
In the 1950s and 1960s, computer operating software and compilers were delivered as a part of hardware purchases without separate fees. At the time, source code—the human-readable form of software—was generally distributed with the software, providing the ability to fix bugs or add new functions. Universities were early adopters of ...
Bitsavers – an effort to capture, salvage, and archive historical computer software and manuals from minicomputers and mainframes of the 1950s, 1960s, 1970s, and 1980s; A brief history of operating systems; Microsoft operating system time-line
Launch of IBM System/360 – the first series of compatible computers, reversing and stopping the evolution of separate "business" and "scientific" machine architectures; all models used the same basic instruction set architecture and register sizes, in theory allowing programs to be migrated to more or less powerful models as needs changed.

Timeline of computing presents events in the history of computing organized by year and grouped into six topic areas: predictions and concepts, first use and inventions, hardware systems and processors, operating systems, programming languages, and new application areas.
Between the mid-1940s and 1950s, various developments were made in computer software.Some of these developments include servo-motors controlled by generated pulse (1949), a digital computer with built-in operations to automatically coordinate transforms to compute radar related vectors (1951), and the graphic mathematical process of forming a shape with a digital machine tool (1952).
