What Is a Third Party Cookie?

Cookie is the small text files that are placed on the web browser. They are used by advertisers and other people to collect different type of information, mostly user identification data. There are two types of cookies: The first party cookie calls to the same domain a user is currently visiting; third party cookies call to a different domain. Since Chrome has the biggest market share, I think it's like 60 or 70% of the whole, you know, global markets, when they do it, it really means that that third party cookies are not going to be used anymore.
