Computers Get Personal

Following my post about the Commercialization of the Web on my social media blog ZenGuide.co.uk, which forms part of the book I am co-authoring with Silvia Cambie on New Trends in International Public Relations, here is the section from the book that outlines the rise of the personal computer. What fascinates me about the history of the Personal Computer (PC) is how it developed from a military machine to something that most of us need to function in the modern world today - and how that evolution has changed society and human culture across the world.

Computers Get Personal

The evolution of technology is a mega-trend today that no business can ignore. A brief tour of the evolution of computers illustrates the importance of keeping your eye on technological developments.

In 1948, IBM´s Selective Sequence Electronic Calculator, which was to calculate the position of the moon for the 1969 Apollo mission to the moon, took up floor space of 25 feet by 40 feet. In 1951, the computer for the US Census Bureau was one of the early commercial computers and it took up 943 cubic feet, selling at US $1million each plus US $185,000 for a high speed printer. By 1968, the cost of a computer was down to US $8,000 with Data General Corp’s Nova which was the size of small writing bureau.[i]

In 1975, the MITS Altair 8800 could be bought by computer hobbyists from Popular Electronics magazine for US $395 as a kit or US $495 pre-assembled[ii]. The next year, Steve Wozniak and Steve Jobs created Apple 1, which sold at just over US $600[iii]. In 1981, Radio Shack’s TRS-82 Model III retailed for US $699. By now, computers were housed in boxes that could be used on a normal office desk and had the shape and set up that we are familiar with today. There is a screen and keyboard and a joystick for navigation. Software came via cassette tape, which was beginning to be replaced by the floppy drive. The data appeared as text or figures and there were no graphics. While available for consumer purchase, it was still the math and science geeks who were the main market demographic for these personal computers.

In 1984, the first Apple Macintosh appeared, with a graphical interface – ie the data could be accessed by activating icons on the screen and navigation was by way of a device called a “mouse”[iv]. At around the same time, Microsoft released the first version of Windows, its own graphical interface sitting on top of MS-DOS, the text-based version of Microsoft software used by most computer manufacturing companies at that time, including IBM and Compaq[v].

By the mid-1990s, you were also getting more bang for your buck when it came to computer processing chips with Intel unveiling its Pentium chip at under US $1,000[vi]. While business and industry had been using computers for decades, plummeting costs, greater processing power and increased ease of use meant that for the first time, it made sense for the public to buy a computer for personal use. People were becoming used to computers from their work environment. It was a natural transition to getting a computer for home use. PCs, as personal computers soon came to be called, were also fun – computer games loaded by CD-ROM became a serious contender to TV-based consoles in 1994[vii]. With PCs arriving in many homes bundled with Internet Explorer for access to the internet, Outlook Express for email and a host of other useful (eg Calendar, Paint and CD-ROMs packed with dictionaries and encyclopedias) and not-so-useful applications (eg Minesweeper and Solitaire games), our personal relationship with our home computers as a source of productivity, fun, information and communication truly began.

In 1995, there were 50 million personal computers sold globally.[viii] By 2000, computer sales in China alone were growing faster than any market in the world, with 4.1 million PCs bought in that one country during the second quarter[ix]. Now in the first decade of the 21^st century, there are over 257 million personal computers sold worldwide[x] and sales are likely to increase over the next few years, in particular of laptops and other mobile computing equipment as affordability, performance and wireless access improve. Gartner, the IT consultants, calculate that emerging markets made up 70% of the growth in overall computer sales and projected that laptop sales during 2008 would grow by 11%. They are confident that a looming global recession would not slow sales[xi]. Experts elsewhere in the industry also seem to agree that mobile computing will bring the next wave of growth for the sector. Loren Loverde, the Director of data firm IDC’s PC Tracker, says, “It will be increasingly important for PC vendors to have a strong portable offering to stay competitive as the market continues its rapid shift to mobile computing.”[xii]

It took 30 years for computers to evolve from military and government use via business and industry to become affordable for a limited geek market, with prices dropping from US $1,000,000 to stabilise around US $700. But from the 1970s onwards, major developments in processing power, size and ease of use surged ahead in leaps and bounds. And with each technological leap and bound, we adapted the way we communicate, relate and work. Even as some businesses are only now thinking about getting their first website (and there are quite a few of those still around), the market is already surging ahead towards online social media and mobile communications. For anyone engaged in business nowadays, it is critical to keep one eye on the latest technological and communications advances if you don’t want to be left behind.
