By definition, I think that market manipulation always happens even the people that doesn't know about it are actively participating in market manipulation, what I mean is that people that are buying goods and services are the reason why the market moves so if there's an advertisement for a product or service then in a way it can be a way that the marketers manipulate the market. So in a way, market manipulation happens everywhere and it's a common occurrence.
Basically, marketing strategy is the key to boosting sales of a product. There are many marketing strategy systems that immediately stick to our memories, so we buy them and apparently this is also experienced by many people, thus moving the market simultaneously and causing big movements. This is something that usually happens in a business, and then it depends on whether the product is able to survive and gain the trust of future consumers
