Britain will start the switch away from analogue television signals on Wednesday, when residents of Whitehaven are turned off. The process will take 4 years to complete with the entire country being digital by 2012, which will see the project completed just as Canada's switch over begins in the summer of 2011. Finland has lead the way completing its Digital implementation in August of this year. Governments are mandating the change because digital cable is a more efficient use of the broadcast airwaves, with several digital channels using the same transmission space as one analogue channel. Cable companies and television manufacturers are no doubt pleased with the change as well, as new equipment is required and higher premiums are involved. The CBC has more details here.
