Technical obsolescence
Technical obsolescence may [occur-endure] when a new product or technology supersedes
the [new-old], and it becomes preferred to [use-discard] the new technology in place
of the old.
Historical examples of [superseding-original] technologies causing obsolescence
include CD-ROM over floppy disk which allowed for [less-greater] storage capacity
and speed, DVD over VHS which allowed for [less-greater] quality and multimedia functions.
On a smaller scale, particular products may become obsolete due to replacement by
a [newer-older] version of the product. [Many-few] products in the computer industry
become obsolete in this manner; for example, Central processing units [frequently-rarely]
become obsolete in favour of newer, [slower-faster] units.
Some products are rendered technologically obsolete due to changes in [related-rival]
products which results in the [function-specification] of the first product being
made unnecessary. For example, buggy whips became [ fashionable-obsolete] when people
started to travel in cars rather than in horse-drawn buggies.


Planned obsolescence
Sometimes manufacturers [deliberately-mistakenly] introduce obsolescence into their
products, with the objective of generating [more-less] sales by [increasing-reducing]
the time between repeat purchases. One example might be producing an appliance which
is [carelessly-deliberately] designed to wear out [within-without] five years of
its purchase, pushing consumers to [represent-replace] it within five years.
Style obsolescence
When a product is no longer [desirable-unpleasant] because it has gone out of the
popular fashion, its style is obsolete. One example is "acid-wash" jeans; although
this article of clothing may still be perfectly [helpful-functional], it is no longer
desirable because style [trends-paths] have moved away from the acid-wash look.
Because of the "fashion cycle", stylistically obsolete products may [eventually-occasionally]
regain [popularity-infamy] and [continue-cease] to be obsolete. A recent example
is flared-leg jeans, which were [derided-popular] in the 1970s, became stylistically
obsolete in the 1980s and returned to popularity in the early 21st century.
