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