You're right CF but in fact "Traffic XXX..." preceded, or at least co-existed with,the widespread "All stations..." era. I've reached the end of my aviation history (mid-80s) but seem to recall that, while "Traffic XXX.." was not universal, it was widely used and obviously well tolerated in an era where people were generally more anal about such things than they are now.
Flying in the US in the early 90s I remember being impressed with the idea of also adding the CTAF (or whatever it was called there at the time) location to the end of the broadcast, the redundancy making for better communication on crowded frequencies. That was a later change for the better here.
We're in danger of having the thread re-titled "communications trivia" or some such
