A complete oscillator consists of the crystal integrated with the
electronics. A loose crystal is just a resonator, and the buyer has to
supply his own electronics. You rarely see the latter any more in
applications other than oven oscillators. The same thing happened in
SAW resonators. About all you can buy now are SAW oscillators.

sorry, what do you mean by "complete oscillator" have outnumbered loose

I got a job in 1975 to design Konel's first synthesized radio, which
was to obsolete their crystal controlled radios. That's over 40 years
ago. The other trend (not mentioned) is that since 20 years ago or
so, complete oscillator sales have vastly outnumbered sales of loose
crystals.

Hi
International’s main business was re-channeling non-synthesized radios and
replacing
broken crystals in various pieces of com gear. It’s been a *lot* of years since
the last of the
non-synthesized radios came out. The business probably has been dropping off
pretty steadily
for many years …

Plenty of other crystal and oscillator manufacturers around.
There's also a change in what kinds of crystals are needed. I suspect most things being built and
designed today use the crystal as a "master oscillator" that is used to drive some sort
of synthesis chain. The need for "I have to have a 12.345,324 Hz crystal" is going away.
