Advertising meat through farms

For example some farms advertised their meat through commercials or documentaries. Some people who work at farm manipulate their audience into believing that their chickens are well taken care of. I feel like we as the audience believe mostly everything the farmers are saying because in the documentary or commercial there is lovely guitar music playing in the background. Of course most of the audience is going to believe a happy advertiser. It is just crazy to me how a lot of people would lie in public through media just to sell a product and gain money.
