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>
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>
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
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>
112 <p>The result of this is <span class="APPLICATION">Privoxy</span>,
113 whose first stable version, 3.0, was released August, 2002.</p>
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>

237 <p>Privoxy is based in part on code originally developed by Junkbusters
238 Corp. and Anonymous Coders.</p>
240 <p>Privoxy heavily relies on Philip Hazel's PCRE.</p>
242 <p>The code to filter compressed content makes use of zlib which is
243 written by Jean-loup Gailly and Mark Adler.</p>
245 <p>On systems that lack snprintf(), Privoxy is using a version written
246 by Mark Martinec. On systems that lack strptime(), Privoxy is using the
247 one from the GNU C Library written by Ulrich Drepper.</p>
