Software can be defined as programmed instructions stored in the memory of stored-program digital computers for execution by the processor. The design for what would have been the first piece of software was written by Ada Lovelace in the 19th century but was never implemented. Alan Turing is credited with being the first person to come up with a theory for software, which led to the two academic fields of computer science and software engineering. The first generation of software for early stored program digital computers in the late 1940s had its instructions written directly in binary code. Early on, it was very expensive when it was in low quantities, but as it became more popular in the 1980s, prices dropped significantly. It went from being an item that only belonged to the elite to the majority of the population owning one. Software would not be where it is today without Bill Gates and Steve Jobs, two pioneers in the industry that had monumental impacts on the history of software. == Before stored-program digital computers ==
