The digital transition of terrestrial broadcast TV has an additional beneﬁt not associated with the two other platforms. Phasing out analog television broadcasting will facilitate more eﬃcient use of the spectrum. Using digital technology allows for much greater output with less spectrum input, freeing up spectrum for other potentially more valuable uses. Those uses are likely to be next generation mobile, including mobile data and video. If a country goes through the transition to digital broadcast television without freeing up spectrum for other uses, it has lost a major beneﬁt of this transition.
