47 <p>A long time ago, there was the <span class="APPLICATION">Internet Junkbuster</span>, by Anonymous Coders and
48 Junkbusters Corporation. This saved many users a lot of pain in the early days of web advertising and user
50 <p>But the web, its protocols and standards, and with it, the techniques for forcing ads on users, give up
51 autonomy over their browsing, and for tracking them, keeps evolving. Unfortunately, the <span class=
52 "APPLICATION">Internet Junkbuster</span> did not. Version 2.0.2, published in 1998, was the last official
53 release, available from Junkbusters Corporation. Fortunately, it had been released under the GNU <a href=
54 "http://www.gnu.org/licenses/old-licenses/gpl-2.0.html" target="_top">GPL</a>, which allowed further development
56 <p>So Stefan Waldherr started maintaining an improved version of the software, to which eventually a number of
57 people contributed patches. It could already replace banners with a transparent image, and had a first version of
58 pop-up killing, but it was still very closely based on the original, with all its limitations, such as the lack
59 of HTTP/1.1 support, flexible per-site configuration, or content modification. The last release from this effort
60 was version 2.0.2-10, published in 2000.</p>
61 <p>Then, some <a href="https://www.privoxy.org/user-manual/copyright.html#AUTHORS" target="_top">developers</a>
62 picked up the thread, and started turning the software inside out, upside down, and then reassembled it, adding
63 many <a href="https://www.privoxy.org/user-manual/introduction.html#FEATURES" target="_top">new features</a>
65 <p>The result of this is <span class="APPLICATION">Privoxy</span>, whose first stable version, 3.0, was released
67 <p>As of 2012 the Junkbusters Corporation's website (http://www.junkbusters.com/) has been shut down, but Privoxy
68 is still actively maintained.</p>
