Anyone know where D-shell connectors first

Interesting thread going on in a local group at the moment about why SCART [1]
sockets are so horrible and nasty (prone to breaking pins, difficult to line
up, prone to falling out etc.) and why something better, like a D-shell
connector, wasn't chosen instead.
SCART was originally known as PERITEL and originated in France.
Make of that what you will :)
To be honest, it's a great idea - and much better than non-European countries
where the typical connectivity is via RF only.
Going source->modulator->tuner->display never did seem like a good idea when
you could just go source->display via separate shielded RGB signals. (The
picture quality I've seen on the typical US setup is piss-poor compared to the
UK, jokes about NTSC aside)
It's just a shame that the connector they picked for the standard is so lousy.
Having looked at some old pricelists, SCART connectors weren't much cheaper
than D-shells - and given that they were typically used on expensive equipment
which only contained a couple of them, the difference couldn't have been
significant at all.
The only thing I can think of (other than it being some odd political
decision) is that you know SCART is SCART; if using D-shells there would have
been a few idiots trying to plug any old computer cable into their equipment.
That hardly seems justification to enforce a nasty connector choice, though.
Assuming that D-shell connectors were around, of course - but if Chuck's right
then they should have been readily available in the mid-70's. Pin spacing is
wider on SCART, so presumably they suffer less from interference - but we all
know that D-shells are perfectly good for video (particularly at TV rates).
