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