The Computer vs. Broadcasting IndustryThe Computer Industry:• the computer industry has achieved the remarkable feat of persuading users that they need to replace their computers very frequently.• This means that users of older computers cannot run the latest software without upgrading their hardware. This inflationary spiral results in rapid obsolescence

It is true that new features can be added, such as widescreen, surround sound and high-definition, but a television essentially remains a television.
