62 <p>A long time ago, there was the <span class="APPLICATION">Internet
63 Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
64 This saved many users a lot of pain in the early days of web
65 advertising and user tracking.</p>
66 <p>But the web, its protocols and standards, and with it, the
67 techniques for forcing ads on users, give up autonomy over their
68 browsing, and for tracking them, keeps evolving. Unfortunately, the
69 <span class="APPLICATION">Internet Junkbuster</span> did not. Version
70 2.0.2, published in 1998, was the last official release, available from
71 Junkbusters Corporation. Fortunately, it had been released under the
72 GNU <a href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
73 target="_top">GPL</a>, which allowed further development by others.</p>
74 <p>So Stefan Waldherr started maintaining an improved version of the
75 software, to which eventually a number of people contributed patches.
76 It could already replace banners with a transparent image, and had a
77 first version of pop-up killing, but it was still very closely based on
78 the original, with all its limitations, such as the lack of HTTP/1.1
79 support, flexible per-site configuration, or content modification. The
80 last release from this effort was version 2.0.2-10, published in
82 <p>Then, some <a href=
83 "https://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
84 "_top">developers</a> picked up the thread, and started turning the
85 software inside out, upside down, and then reassembled it, adding many
87 "https://www.privoxy.org/user-manual/introduction.html#FEATURES"
88 target="_top">new features</a> along the way.</p>
89 <p>The result of this is <span class="APPLICATION">Privoxy</span>,
90 whose first stable version, 3.0, was released August, 2002.</p>
91 <p>As of 2012 the Junkbusters Corporation's website
92 (http://www.junkbusters.com/) has been shut down, but Privoxy is still
93 actively maintained.</p>
