‘Product placement’ or ‘brand placement’, which is the correct term?

I’ve always preferred ‘brand placement’. If a detergent were to be used in a movie then it would be a real brand (Bold, Tide, or the like) and not just a box with ‘detergent’ written on it. But, as it turns out, I’m in the minority. My preference doesn’t count. The term ‘product placement’ is the one most used in the industry. Easily confirmed by comparing the two terms in Google Trends, where ‘product placement’ outstrips ‘brand placement’ by fifty to one.
