101 A long time ago, there was the <a href=
102 "http://www.junkbusters.com/ijb.html" target="_top"><span class=
103 "APPLICATION">Internet Junkbuster</span></a>, by Anonymous Coders
104 and <a href="http://www.junkbusters.com/" target="_top">Junkbusters
105 Corporation</a>. This saved many users a lot of pain in the early
106 days of web advertising and user tracking.
109 But the web, its protocols and standards, and with it, the
110 techniques for forcing ads on users, give up autonomy over their
111 browsing, and for tracking them, keeps evolving. Unfortunately, the
112 <span class="APPLICATION">Internet Junkbuster</span> did not.
113 Version 2.0.2, published in 1998, was (and is) the last official <a
114 href="http://www.junkbusters.com/ijbdist.html#release" target=
115 "_top">release</a> available from <a href=
116 "http://www.junkbusters.com" target="_top">Junkbusters
117 Corporation</a>. Fortunately, it had been released under the GNU <a
118 href="http://www.gnu.org/licenses/old-licenses/gpl-2.0.html"
119 target="_top">GPL</a>, which allowed further development by others.
122 So Stefan Waldherr started maintaining an improved version of the
123 software, to which eventually a number of people contributed
124 patches. It could already replace banners with a transparent image,
125 and had a first version of pop-up killing, but it was still very
126 closely based on the original, with all its limitations, such as
127 the lack of HTTP/1.1 support, flexible per-site configuration, or
128 content modification. The last release from this effort was version
129 2.0.2-10, published in 2000.
133 "http://www.privoxy.org/user-manual/copyright.html#AUTHORS" target=
134 "_top">developers</a> picked up the thread, and started turning the
135 software inside out, upside down, and then reassembled it, adding
137 "http://www.privoxy.org/user-manual/introduction.html#FEATURES"
138 target="_top">new features</a> along the way.
141 The result of this is <span class="APPLICATION">Privoxy</span>,
142 whose first stable version, 3.0, was released August, 2002.
