The article is devoted to Sunlight chain which once revolutionized the jewelry market by selling diamond pendants for several thousand rubles and distributing jewelry at grocery store checkouts. But the company went too far with marketing experiments: due to advertising about “sales for free” and the liquidation of the network, which has not been happening for many years, the company has become an Internet meme. The emergence of an accessible Internet, the development of social networks and the tightening of competition today forces various companies to resort to rather radical ways of “fighting” for an audience. In the article the advantages and disadvantages of disinformation PR technique are considered on the example of Sunlight's intentional launching of deliberately fake news into the information field.
