A direct comparison ad would be one where the company says, " We're better than this other company;we're better than this other product." This is not as common, apparently, in Japanese advertising; it's very common in American advertising.
直接比较广告是公司说,“我们比这家公司好; 我们比其他产品好。 ” 这显然在日本广告中并不常见;这在美国广告中很常见。
