Media Communications vs Human Communications

Is seeing or hearing something in the media as effective as seeing or hearing it in real life? Talking heads on news programs and many other people tell you their opinions on television, radio and newspapers. It makes them seem more important, therefore their opinion more valid, that they are being broadcast to the public. Would you think the same about someone’s opinion of view by talking to them one on one, rather than witnessing it through a media outlet? Also, advertising through media can make products seem much more important and appealing than real life due to many special effects and exaggerated uses and benefits of a product (Example: Beer commercials with big parties and girls in bikinis). Is it fair to advertise a product through media as more than it really is? Are message conveyed with a better response through media communications rather than human communications?
