Here is an article written for Creative Review by Gordon Comstock and here are some excerpts from it.

The modern illustrator offers brands a vital shot of personality. Rather than selling out, it’s adverting that gives them so much freedom.

In harmony with consuming. This is just one of the advantages of the modern illustrator: he (or she) comes with a fashionable bag of personality. His hand is freer than his forebear’s. If he likes to draw weirdly-shaped hamburger-people. he is allowed, nay, encouraged to do so. Ian Stevenson and David Shrigley open the door on this style, which art historians probably won’t ever call the Knowingly Naive School. It’s prominence is part of a deeper trend in adverting, which is the movement from represenation to expression.
