81 <p>A long time ago, there was the <span class="APPLICATION">Internet
82 Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
83 This saved many users a lot of pain in the early days of web
84 advertising and user tracking.</p>
86 <p>But the web, its protocols and standards, and with it, the
87 techniques for forcing ads on users, give up autonomy over their
88 browsing, and for tracking them, keeps evolving. Unfortunately, the
89 <span class="APPLICATION">Internet Junkbuster</span> did not. Version
90 2.0.2, published in 1998, was the last official release, available from
91 Junkbusters Corporation. Fortunately, it had been released under the
92 GNU <a href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
93 target="_top">GPL</a>, which allowed further development by others.</p>
95 <p>So Stefan Waldherr started maintaining an improved version of the
96 software, to which eventually a number of people contributed patches.
97 It could already replace banners with a transparent image, and had a
98 first version of pop-up killing, but it was still very closely based on
99 the original, with all its limitations, such as the lack of HTTP/1.1
100 support, flexible per-site configuration, or content modification. The
101 last release from this effort was version 2.0.2-10, published in
104 <p>Then, some <a href=
105 "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
106 "_top">developers</a> picked up the thread, and started turning the
107 software inside out, upside down, and then reassembled it, adding many
108 <a href="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
109 target="_top">new features</a> along the way.</p>
111 <p>The result of this is <span class="APPLICATION">Privoxy</span>,
112 whose first stable version, 3.0, was released August, 2002.</p>
114 <p>As of 2012 the Junkbusters Corporation's website
115 (http://www.junkbusters.com/) has been shut down, but Privoxy is still
116 actively maintained.</p>
