The Past The Personal Computer’s past is taken primarily from my previous book: A Short History of the Personal Computer, published in 2013 and available on Amazon.com. It focusses on the growth in global sales volume from its inception in 1975 to the peak in its sales volume in 2011. In A Short History of the Personal Computer, our story stressed the importance of the sequence of Applications Software created for the PC. We believe it was this sequence of software innovations that was the key driver of the popularity of the PC, and led it to increasing sales, time and again, over the PC’s 36-year history from 1975 to 2011. However, none of this success would have been possible without two linked series of computer innovations that provided the platform for the series of application software that we have highlighted in this book: (1) The developments of the microprocessor hardware, led by Noyce, Moore and Groves at Intel; and (2) The development of the PC Operating Systems, led by Bill Gates and Paul Allen at Microsoft. Because of the Importance of these innovations to the success of the Personal Computer, in this book, we have included a review of the history of both the PC hardware and the PC software in an Appendix, Appendix F. The Personal Computer, Past, Present and Future The Present A Short History of the Personal Computer was published using Amazon’s Create Space publishing system in the fall of 2013. At that time, we concluded by observing that in 2011 and 2012 there was evidence of a peaking in global PC sales in 2011 at 365 million units. In 2017, we can see that this peaking has occurred and indeed we are now in a period of precipitous decline in global PC Sales. We have added a section describing the continuity of PC global Sales from 2007 to 2017. It includes some elaboration on comments in A Short History of the Personal Computer on the causes of the decline in PC sales after 2011, which we attribute to (1) the arrival of the Smartphone that took away much of the PC’s function as the primary digital communication device for internet users; (2) the lengthening of the PC replacement cycle, and (3) The lack of another mega App. In this book we elaborate on 5 these causes of the PC’s decline. 6 The Personal Computer, Past, Present and Future The Future Looking to the future, we explore possible sources of renewed growth in overall PC sales. We conclude with a list of positive things to watch for that might indicate a halting of the slide in PC sales and growth in the future. 7 The Personal Computer, Past, Present and Future 8 Table of
