81
82       <p>A long time ago, there was the <span class="APPLICATION">Internet
83       Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
84       This saved many users a lot of pain in the early days of web
85       advertising and user tracking.</p>
86
87       <p>But the web, its protocols and standards, and with it, the
88       techniques for forcing ads on users, give up autonomy over their
89       browsing, and for tracking them, keeps evolving. Unfortunately, the
90       <span class="APPLICATION">Internet Junkbuster</span> did not. Version
91       2.0.2, published in 1998, was the last official release, available from
92       Junkbusters Corporation. Fortunately, it had been released under the
93       GNU <a href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
94       target="_top">GPL</a>, which allowed further development by others.</p>
95
96       <p>So Stefan Waldherr started maintaining an improved version of the
97       software, to which eventually a number of people contributed patches.
98       It could already replace banners with a transparent image, and had a
99       first version of pop-up killing, but it was still very closely based on
100       the original, with all its limitations, such as the lack of HTTP/1.1
101       support, flexible per-site configuration, or content modification. The
102       last release from this effort was version 2.0.2-10, published in
103       2000.</p>
104
105       <p>Then, some <a href=
106       "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
107       "_top">developers</a> picked up the thread, and started turning the
108       software inside out, upside down, and then reassembled it, adding many
109       <a href="http://www.privoxy.org/user-manual/introduction.html#FEATURES"
110       target="_top">new features</a> along the way.</p>
111
112       <p>The result of this is <span class="APPLICATION">Privoxy</span>,
113       whose first stable version, 3.0, was released August, 2002.</p>
114
115       <p>As of 2012 the Junkbusters Corporation's website
116       (http://www.junkbusters.com/) has been shut down, but Privoxy is still
117       actively maintained.</p>
