Unintelligent Marketing Campaigns

When a new brand is created, often from a set of sub-brands, this is often accompanied by a brute-force marketing campaign to make the new brand sit squarely in the minds of potential new consumers. 

A similar approach is often seen when said company is then sold on to new owners who want to add value by "saturation marketing" to put the brand more squarely in the market consciousness.

Unfortunately, this is not very effective as techniques used are often crude and generic.

One example would be the campaign used by Blackstone following their acquisition of Enverus. This was a "saturation marketing" campaign which did not add, but rather detracted, from the overall brand.  There are many more examples of similar ineffective marketing campaigns.
