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