  81
  82       <p>A long time ago, there was the <a href=
  83       "http://www.junkbusters.com/ijb.html" target="_top"><span class=
  84       "APPLICATION">Internet Junkbuster</span></a>, by Anonymous Coders and
  85       <a href="http://www.junkbusters.com/" target="_top">Junkbusters
  86       Corporation</a>. This saved many users a lot of pain in the early days
  87       of web advertising and user tracking.</p>
  88
  89       <p>But the web, its protocols and standards, and with it, the
  90       techniques for forcing ads on users, give up autonomy over their
  91       browsing, and for tracking them, keeps evolving. Unfortunately, the
  92       <span class="APPLICATION">Internet Junkbuster</span> did not. Version
  93       2.0.2, published in 1998, was (and is) the last official <a href=
  94       "http://www.junkbusters.com/ijbdist.html#release" target=
  95       "_top">release</a> available from <a href="http://www.junkbusters.com"
  96       target="_top">Junkbusters Corporation</a>. Fortunately, it had been
  97       released under the GNU <a href=
  98       "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target=
  99       "_top">GPL</a>, which allowed further development by others.</p>
 100
 101       <p>So Stefan Waldherr started maintaining an improved version of the
 102       software, to which eventually a number of people contributed patches.
 103       It could already replace banners with a transparent image, and had a
 104       first version of pop-up killing, but it was still very closely based on
 105       the original, with all its limitations, such as the lack of HTTP/1.1
 106       support, flexible per-site configuration, or content modification. The
 107       last release from this effort was version 2.0.2-10, published in
 108       2000.</p>
 109
 110       <p>Then, some <a href=
 111       "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
 112       "_top">developers</a> picked up the thread, and started turning the
 113       software inside out, upside down, and then reassembled it, adding many
 114       <a href="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
 115       target="_top">new features</a> along the way.</p>
 116
 117       <p>The result of this is <span class="APPLICATION">Privoxy</span>,
 118       whose first stable version, 3.0, was released August, 2002.</p>
