82 <a name="AEN1514">7.2. History</a>
85 A long time ago, there was the <span class="APPLICATION">Internet
86 Junkbuster</span>, by Anonymous Coders and Junkbusters Corporation.
87 This saved many users a lot of pain in the early days of web
88 advertising and user tracking.
91 But the web, its protocols and standards, and with it, the
92 techniques for forcing ads on users, give up autonomy over their
93 browsing, and for tracking them, keeps evolving. Unfortunately, the
94 <span class="APPLICATION">Internet Junkbuster</span> did not.
95 Version 2.0.2, published in 1998, was the last official release,
96 available from Junkbusters Corporation. Fortunately, it had been
97 released under the GNU <a href=
98 "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target=
99 "_top">GPL</a>, which allowed further development by others.
102 So Stefan Waldherr started maintaining an improved version of the
103 software, to which eventually a number of people contributed
104 patches. It could already replace banners with a transparent image,
105 and had a first version of pop-up killing, but it was still very
106 closely based on the original, with all its limitations, such as
107 the lack of HTTP/1.1 support, flexible per-site configuration, or
108 content modification. The last release from this effort was version
109 2.0.2-10, published in 2000.
113 "https://www.privoxy.org/user-manual/copyright.html#AUTHORS"
114 target="_top">developers</a> picked up the thread, and started
115 turning the software inside out, upside down, and then reassembled
116 it, adding many <a href=
117 "https://www.privoxy.org/user-manual/introduction.html#FEATURES"
118 target="_top">new features</a> along the way.
121 The result of this is <span class="APPLICATION">Privoxy</span>,
122 whose first stable version, 3.0, was released August, 2002.
125 As of 2012 the Junkbusters Corporation's website
126 (http://www.junkbusters.com/) has been shut down, but Privoxy is
127 still actively maintained.
