我之前有看到的一个说法是
AGB的样本年龄比TNS偏大
不过没办法，即使样本空间小
在没有别的更好的参考的情况下
电视台和广告商还是要看这俩收视
你听到的说法可能是谣传
我是没听过韩饭这麽说过
（可能我孤陋寡闻，但推上我认识的韩饭里 没人这麽说过）
有位专家应 城市猎人 和 最爱 的粉丝的要求（2个竞争是不是很激烈啊？）
对AGB和TNS的收视率写下了他的分析，
全文如下：（他文章里并没有提到亲说的样本年龄的事。。我是觉得不太可能啦。。）

South Korean TV Ratings: TNmS vs. AGB Nielsen
by: jbarky on Jun 21, 2011
TV ratings are always significant to gauge which programs are more popular for broadcasting companies, advertising companies, and also fans. Currently for the Thursday-Friday slight of dramas “Greatest Love” and “City Hunter” are competing for number one in viewers for that time slot. A user had asked me why South Korea has two different ratings and I wrote this short piece in hopes of giving an answer.
Originally TV ratings were dominated by one company called Media Service Korea. In 1999, TNS Media Korea began to publically provide TV rating information that improved on several problems that had occurred because of Media Service Korea’s dominance.
Then MSK was acquired by AC Nielsen and the competition between the two companies began. As of 2005, AC Nielson and AGB had merged to create AGB Nielson research.
TNS Media Korea on the other hand changed their name to TNmS in 2010.
（在这之前都在说他们的前身和历史）
Currently AGB Nielson has a total of 2050 households that are being researched for TV ratings. The breakdown is the following: Seoul 550, Busan 250, Daegu 200, Kwang Ju 160, Dae Jun 160 and other smaller cities 290.
这里说AGB的取样数目是 2050个家庭：首尔 550家，釜山 250家， 大邱 200家， 光州 160家，大均 160家， 其他小城市 290家。
TNmS is also similar in number of households as they have 2000 households spread out around Korea.
TNmS也类似，他们有2000家，遍及韩国。
Both companies use a research tool called People Meter that is attached to a Receptor. Any person can be included in the research, but families that have a member involved in the broadcasting business in some way are excluded.
2家都是用“人尺”（People Meter）接在每家的接收器的方法。家中任何成员都可参与，但AGB和TNS的员工家庭不能参与。
The two companies also had their share of legal battles. AGB Nielson accused TNmS of having rigged some of the research information. The first court accepted the accusations in September 17h of 2009 but TNmS have appealed.
这里提到了之前那个韩饭说的TNS人为操纵数据的事，还被AGB告，TNS也提起上诉。
Now the question is, what makes the ratings have 2~3% differences between the two research companies? For some, they believe that the reason for this difference is that TNmS visits the households and includes “guests” that are watching TV into their studies thus increasing the percentage of certain TV Show, while AGB Nielson does not. However, the “real” reason for this difference has yet to be determined. It is also a source of controversy because these percentage differences would mean a lot for advertising companies or broadcasting companies.
他这里说到，AGB和TNS 2~3%的差距，有人认为是TNS允许家庭成员外的“客人”参与造成的。。但是“真正”的理由还是不能确定。这也是争议的由来，因为百分比对广告公司来说意义很大。（所以那位韩饭没说错。。TNS有人为作假的争议因素在里面。。）
Now this is my own opinion but, consider these facts. If TNmS and AGB Nielson had the same households in their research we would probably see identical numbers. Otherwise, you might see few percentage differences like we do now. A really simple explanation, I know, but it makes sense to me :P. Also, for any type of research you always leave open that “margin of error,” and also outliers.
