""Critics, in the pay of private galleries, began to write catalog introductions. This became a major source of income, particularly because dealers paid considerably more than magazines did. And it was worth it to the galleries because...they did not have to "wait for museum shows and their accompanying catalog. (They) get the ball rolling by simply hiring a critic and doing the job in-house...which guarantees a positive treatment." And they also improved the relationships with the critics... Indeed, most of the commentary was no longer independent or disinterested, but had become a glorified kind of publicity or advertising.""
