 106         <p>
 107           A long time ago, there was the <a href=
 108           "http://www.junkbusters.com/ijb.html" target="_top"><span class=
 109           "APPLICATION">Internet Junkbuster</span></a>, by Anonymous Coders
 110           and <a href="http://www.junkbusters.com/" target="_top">Junkbusters
 111           Corporation</a>. This saved many users a lot of pain in the early
 112           days of web advertising and user tracking.
 113         </p>
 114         <p>
 115           But the web, its protocols and standards, and with it, the
 116           techniques for forcing ads on users, give up autonomy over their
 117           browsing, and for tracking them, keeps evolving. Unfortunately, the
 118           <span class="APPLICATION">Internet Junkbuster</span> did not.
 119           Version 2.0.2, published in 1998, was (and is) the last official <a
 120           href="http://www.junkbusters.com/ijbdist.html#release" target=
 121           "_top">release</a> available from <a href=
 122           "http://www.junkbusters.com" target="_top">Junkbusters
 123           Corporation</a>. Fortunately, it had been released under the GNU <a
 124           href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
 125           target="_top">GPL</a>, which allowed further development by others.
 126         </p>
 127         <p>
 128           So Stefan Waldherr started maintaining an improved version of the
 129           software, to which eventually a number of people contributed
 130           patches. It could already replace banners with a transparent image,
 131           and had a first version of pop-up killing, but it was still very
 132           closely based on the original, with all its limitations, such as
 133           the lack of HTTP/1.1 support, flexible per-site configuration, or
 134           content modification. The last release from this effort was version
 135           2.0.2-10, published in 2000.
 136         </p>
 137         <p>
 138           Then, some <a href=
 139           "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
 140           "_top">developers</a> picked up the thread, and started turning the
 141           software inside out, upside down, and then reassembled it, adding
 142           many <a href=
 143           "http://www.privoxy.org/user-manual/introduction.html#FEATURES"
 144           target="_top">new features</a> along the way.
 145         </p>
 146         <p>
 147           The result of this is <span class="APPLICATION">Privoxy</span>,
 148           whose first stable version, 3.0, was released August, 2002.
