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