CMOS

I remember working with this low power technology
http://en.wikipedia.org/wiki/CMOS back in the mid-1970s when it first came out.
Seems to be long-lived.

The Archers

This one didn't turn out as I expected. By capitalising both words, I hoped to
pick up references to the BBC radio "soap" "The Archers" which started in
1950.

Godfather

The growth after around 1970 may be because of the books/films written by
Mario Puzo

anti-oppressive practice

This is an interesting modern concept in Social Work

Social work is known to be a �caring profession� but ... there may be a �care
versus control� issue, because where there is care there is responsibility, and
therefore control, and power. Practitioners need to be fully aware of the power
(im)balance between service users and providers in order to work in an anti-
oppressive manner. Otherwise, so-called anti-oppressive practice can be
criticised as �a gloss to help [social work] to feel better about what it is
required to do�

Mountain bike

People were riding bicycles up mountains almost as soon as the bike was
invented but the term seems to be unknown before around 1982

Are we nearly there yet?

This expression, commonly attributed to children on long car jouneys goes in
and out of fashion.
