In reply to Martin Hore:
Good question.
I actually started climbing by soloing in a local quarry in plimmies. This was in the late 70s, so I'm probably one of the last.
The big things that were happening around that time were: widespread use of chalk; the introduction of camming devices; second generation rock boots; belay devices; climbing walls.

I'd say you're right. Lots of incremental improvement since, but no really radical innovations.
A 2.5 Friend was one of my early gear purchases, but for a long time it was also my only camming device . "Quantity has a quality all of its own" though, and the complete set of cams from 10mm upwards that I now possess, with doubles if I can be bothered to carry them, does make life a lot easier than one cam and a few hexes.
Similarly, Fires were better than EBs and Miuras are better still, but probably not as much of a jump as from plimmies to EBs.
The Sticht Plate had just come into general use, and until/unless assisted locking devices become common for trad I'd say nothing much has changed there.
Climbing walls were rudimentary compared to today's, but I'd almost say brick edge traversing - if your finger tendons survive it - is more relevant training for rock than plastic blob dyno-ing. Crimpy round-about-vertical is the only style in which I can sometimes burn Kids These Days off at bouldering walls.
The NEXT big thing? Dunno. Something similar to avalanche airbags but with helium, eliminating the need for ropes etc. entirely?
