<Anchor> The

competition for public relations among domestic beer companies has turned into a mud fight. It is expanding into police investigations by removing or damaging the other company's billboards without permission.

Reporter Han Ji-yeon reports.

<Reporter> In

front of a restaurant in Seongnam Moran Market, a man from a van loads a life-size billboard in the trunk of a famous celebrity promoting a new product of Obi Beer.

As a result of vehicle inquiry, it was owned by HITEJINRO Corporation.

Near Anyang Beomgye Station, a man pulls out a lot of promotional materials, and another man has a hard time tearing something off the exterior wall of the business.

This is HITEJINRO's beer LED promotional material, and the men in the video were Obi Beer employees.

Obi Beer asked the police to investigate this matter, and Hite Beer is in a position to respond face-to-face.

[Ob Beer officials: Isn't it possible to systematically plan business disruptions at the company level…? .]

[Hite Brewery official: I can only think of scratching us from a sense of crisis.]

Marketing slander to competitors is not a thing of yesterday and today.

Namyang Dairy is being investigated by the prosecution for systematically leaving slanderous comments on competitors, while chicken rivals BBQ and BHC exchanged about 20 lawsuits for 7 years, while home appliance counterparts Samsung and LG Electronics also engaged in a non-discharge. They reported each other and were investigated.

[Seo Ji-young: I think we should do it while doing such a war and committing illegality. I don't think no one will buy it. Then it won't sell more.] It

is pointed out that negative marketing that undermines competitors can eventually lead to consumer distrust and disgust, which can cause damage to themselves as well.
