Disrespectful, inconsiderate, and at times aggressive and ultimately hurtful marketing to help manufacturers and retailers take as much advantage of consumers as possible.
Decades ago every item sold in a store had a price tag, now the retailers don't waste energy, thus money, sticking a price tag on each item or at least displaying a sign that informs consumers the price. That is just one example of predatory marketing. My definition of 'predatory marketing' is different than a more common one which states that it is any activity instigated—usually, by the larger manufacturer—to tangibly harm or eliminate smaller competitiors.
