At least in advertising, unlike news reporting, one can get out the information that he wants to get out. Besides, it reaches a much larger audience than the usual "person to person" diplomacy, and all you need to participate is money.
廣告的好處是：只要你有錢，就可以買時段、買版面；其次，它是一種大眾傳播，影響的人數比遊說、外交等「人對人」的方式來得多。此外，新聞是由別人的角度介紹；廣告則是由我們的立場發言，更能傳達我們所要強調的訊息。
