One of the basic truths in advertising is that ads are more credible when the brand or product is supported by public relations - especially in the form of third party endorsements (real or implied) such as a review.
Meaning that manufacturers know that running an ad in an issue that carries a review provides a measurable way to leverage their investment.
At the same time, as Pableson pointed out, publishers know that people read magazines to find out about the latest and greatest - this is especially true in the world of buff books (specialty or enthusiast mags)
So a model has evolved based on this "synergy" - the third leg of which are the tradeshows where each year the hot new things are discovered and the review calendar is planned for the year.
Along with hifi, I am into photography, sailing, gardening, cooking and wine and I assure you this same model is at work in all of them.
