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