The big questions are how many households, TV-sets, antennas, apartments, offices will be effected by the transition.
The local news channel WCCO in Minnesota reported on the subject. Estimating that around 70 million TV-sets in the US are analog only. And about 66% of the countries households have an analog TV-set. I have earlier got the information from NAB that 18.7 % of households in the US have only analog reception.
