Also in France we have a tax on CD-R, DVD-R, hard drives, mp3 players which is given to the music companies to compensate their losses from pirating (you pay that tax whether you pirate or not. And still haven't the right to pirate after paying it). The ISP also give 1% of their income to those companies. So yes I think taxing the search engines is the logical next step.
The next logical step is that the government forces you to listen to 4 hours of music a day, and pay for it, so that flagging creative industries are supported...
