  90
  91       <p>A long time ago, there was the <a href=
  92       "http://www.junkbusters.com/ijb.html" target="_top"><span class=
  93       "APPLICATION">Internet Junkbuster</span></a>, by Anonymous Coders and
  94       <a href="http://www.junkbusters.com/" target="_top">Junkbusters
  95       Corporation</a>. This saved many users a lot of pain in the early days
  96       of web advertising and user tracking.</p>
  97
  98       <p>But the web, its protocols and standards, and with it, the
  99       techniques for forcing ads on users, give up autonomy over their
 100       browsing, and for tracking them, keeps evolving. Unfortunately, the
 101       <span class="APPLICATION">Internet Junkbuster</span> did not. Version
 102       2.0.2, published in 1998, was (and is) the last official <a href=
 103       "http://www.junkbusters.com/ijbdist.html#release" target=
 104       "_top">release</a> available from <a href="http://www.junkbusters.com"
 105       target="_top">Junkbusters Corporation</a>. Fortunately, it had been
 106       released under the GNU <a href=
 107       "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target=
 108       "_top">GPL</a>, which allowed further development by others.</p>
 109
 110       <p>So Stefan Waldherr started maintaining an improved version of the
 111       software, to which eventually a number of people contributed patches.
 112       It could already replace banners with a transparent image, and had a
 113       first version of pop-up killing, but it was still very closely based on
 114       the original, with all its limitations, such as the lack of HTTP/1.1
 115       support, flexible per-site configuration, or content modification. The
 116       last release from this effort was version 2.0.2-10, published in
 117       2000.</p>
 118
 119       <p>Then, some <a href=
 120       "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
 121       "_top">developers</a> picked up the thread, and started turning the
 122       software inside out, upside down, and then reassembled it, adding many
 123       <a href="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
 124       target="_top">new features</a> along the way.</p>
 125
 126       <p>The result of this is <span class="APPLICATION">Privoxy</span>,
 127       whose first stable version, 3.0, was released August, 2002.</p>
