Computers didn't have an impact on everyday life in the 1950s because they were too large and expensive for personal use.
Before the introduction of the microprocessor in the early 1970s, computers were generally large and expensive systems owned by large corporations, universities, government agencies, and similarly sized institutions. The end users generally did not interact directly with the machine, but rather prepared tasks for the computer, in off-line equipment such as card punches. Several assignments for the computer would be collected and processed in batches. After the work was over, users could pick up the results. In some cases it could take hours or days between submitting a job to the computer center and receiving the output.
