vuo writes: At 04:00, 1 September 2007, all analog television networks were shut down, and the switchover to digital television has been completed. Watching television requires a digital decoder, such as a set-top box, a television with an integrated decoder, or a computer with a digital TV card. Currently, the national broadcasting corporation Yleisradio (YLE), which operates five digital channels, is funded by a television licence fee (208.15 per year per household). However, a consequence of digitalization is that nearly every device with a screen is potentially a television set. Minister of Communications Suvi Lindén has questioned the current policy, and promotes funding of YLE from the national budget and reducing the production of domestic programmes. YLE's director, also a former Microsoft PR director Mikael Jungner (sd.) opposes the plans.
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
