The few DVD's I have on various machines and technique do have an advantage over the printed media. And books aren't cheap to produce. Their advantage is that they can be taken into the shop to be used as reference.
And some data, such as tables and charts and diagrams, are best presented on paper. As long as there is a continual demand for higher quality materials from users, things will improve. The problem is that the decades-old imprint of Popular Mechanics (both in regard to design styles and intellectual level) set the tone.
