5. THE EMERGENCE OF PROGRAMMING

The first software was written by Ada Lovelace
The first theory concerning the software, was
proposed by English mathematician Alan
Turing in 1936
The first electronic computers 1940-1950-ies
were preprogrammable by switching the toggle
switches and re-cabling
The first program stored in computer memory,
was launched on 21 June 1941.
In 1950-e years the first high-level
programming languages had appeared.

6. THE EMERGENCE OF PROGRAMMING

By the mid 50-ies there had already fully developed
software contracting
The first software development company was founded
in 1959 by Roy Natom and Fletcher Jones Computer
Sciences Corporation.
The emergence in the 1970-ies the first personal
computers (Altair 8800) had created prerequisites for
the emergence of a mass market software.
