David, I never started following circuit racing until about 69 so that is a lttle before my time. Have learnt a lot of interesting stuff on this forum from the people that where around then participating. {drivers, spectators, crews, journos, preparation people]
But the magazines in the 60s and 70s were far more balanced and covered more events than now. Which is wrong.
A fair bit before my time too, as my first meeting was at Sandown in '73 at the ripe age of 10.
In the course of my research on Australian racing, I have purchased a fair few magazines from the era.
The lack of balance is wrong, but I can understand how it has become as it is. From July 1968, the tide started to turn here and it went from being a sport to being a business. The teams involved in all the major and popular categories now have employees whose job it is to market the team. Therefore they push themselves on the motorsport press and it is a lot easier to cover those categories than the ones where you have to actually chase a story.
