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