The evolution of human computation, from ancient tally sticks to the modern marvels of technology, traces a fascinating journey. The series of videos below delves into the rich tapestry of computing history, from Stonehenge and abacuses to the revolutionary era of mainframes. Alan Turing's groundbreaking algorithms with the concept of a stored program computer and the commercial dawn of computers in the mid-20th century set the stage for a transformative period in business computing.

Amid the cultural upheavals of the 1960s, IBM's 360 emerged as the harbinger of modern mainframes, reshaping business computing and empowering endeavors like NASA's space missions.

The mainframe's impact on real-time transaction processing in the 1970s laid the foundation for critical systems like credit card authorizations and airline reservations.

The mainframe was the outgrowth of a IBM's cultural commitment to responsible computing and architecture built around business needs. IBM's promise, made in 1964, that whatever you wrote for their mainframe would continue to run into the future has been faithfully kept. The ability to run legacy workloads without constant upgrades is a testament to the mainframe's enduring legacy. The 1980s and 1990s were a time of growth, expansion, and response to the challenges posed by distributed computing. The mainframe persisted, adapting to change and providing reliable, secure, and scalable computing.

As the 21st century began, the internet and global commerce expanded exponentially, emphasizing the need for security, reliability, and manageability—the mainframe's forte. Globalization and the push for cloud computing posed challenges, but the mainframe's attributes of security, scalability, and reliability remained unmatched. The introduction of Linux to the mainframe platform showcased its adaptability to new technologies. The mainframe's role in business computing prevailed as organizations realized its unique capabilities in handling massive amounts of data and transactions.

The mainframe community anticipates continued growth and relevance in the coming years, with a new generation of professionals entering the field through educational initiatives. The mainframe's ability to provide a secure, scalable, and cost-effective platform positions it as a cornerstone of the IT ecosystem. The mainframe's future appears bright, with its offering unlimited opportunities for those interested in business computing. IBM's ongoing investment in the platform ensures that the mainframe will continue to be a vibrant and integral part of the ever-evolving IT landscape.
