Product placement seems to have found a way into books.
It was one of the more startling aspects of the original James Bond books. He didn't just use an 'expensive cigarette lighter' and drive a 'sporty car', he used a Ronson and had a Bentley with an Amherst Villiers supercharger.
You'll also find mention of Gordon's gin, Citroën, Morland cigarettes, and Taittinger champagne.
This was certainly not the norm for literature in 1953, but was a conscious choice by Fleming to root Bond in reality, albeit a rather upscale one.
