The initial impact of computers was in the area of entertainment.If you walked by a video arcade in the early 1980s，you could not have failed to notice that the use of video games was growing at what some considered an alarming rate.In 1981the movie industry grossed $3billion，video games took in an estimated $6billion.That gives you some idea of just how big the computer industry bad become.Video games employ the same technology as personal computers，and indeed many who bought personal computers did so primarily for playing games at home，thus saving their quarters.Though video games are not as popular as they were a few years ago，they did provide consumers with their first real reason to buy PCs.
A more recent computer innovation，desktop publishing，supplies one good reason for those who write for a living to buy a PC.Desktop publishing is a deceptively simple description for an extremely complex group of hardware and software tools.You can now write text，edit text，draw illustrations，incorporate photographs，design page layouts，and print a finished document with a relatively inexpensive computer and laser printer.Although the new technology offers new freedom，there is a price to be paid for this freedom.
With total control comes total responsibility.In fact，the issue of social responsibility in our new computer age has long been a topic of debate among computer enthusiasts.Some people are concerned with the long-term social effects of the so-called computer revolution.Ironically，many PC pioneers who built and marketed the first machines were 60s-style.advocates of social change.They claim that while personal computer technology has the potential to make society more equal，it’s having the opposite effect since upper-middle-class people can afford them and lower-class people cannot.
In addition，the ways that computers are used to monitor the activities of their users have evoked anxiety about the machine.Over 7million Americans now have their work paced，controlled，and monitored by computers.A computer is more restrictive and powerful in the way it controls people than the old-fashioned assembly line.This can lead to what some have called ’tech-stress’.Irritated eyes，back problems，and other physical symptoms have also been associated with the extensive use of computers.Although the personal computer may not have had the impact some predicted a decade ago，the combination of computer technology with satellites and cable does promise innovations in the mass media that would have seemed astonishing just a few short years ago.
