  cookie as inspiration in 1994.

  a site, and cookies use this data to help build
  targeted ads that you might enjoy.

First-Party vs. Third-Party Cookies

• First-party cookies are directly created by the
  website you are using. These are generally safer,
  as long as you are browsing reputable websites or
  ones that have not been compromised.
• Third-party cookies are more troubling. They are
  generated by websites that are different from the
  web pages users are currently surfing, usually
  because they're linked to ads on that page.
