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