advertorial
An article or editorial that has been written for the purpose of promoting a product or service. The word itself is a combination of "advertisement" and "editorial." Often the piece will avoid a tone with overt bias.
I had read a whole page about vitamins in the news magazine before realizing the story was just an advertorial.
advertorial sage
One who thrives in the commercial throes of cleaning, polishing, and aesthetic products and gadgetry, while possessing and embodying the wisdom of an edified persona.
The advertorial sage's day job seems contrary to her true passion and spirit, leading one to expect greatness from such trials.
