The DSO launch in Abuja signals the commencement of full switchover from analogue to digital broadcasting in Nigeria.
What this implies is that residents of the Federal Capital Territory (FCT) would now enjoy 30 free channels with the aid of a set-top-box.
The switch is coming after several unsuccessful attempts by previous administrations to migrate from analogue to digital broadcasting.
Vice President Yemi Osinbajo who represented his principal at the event said the switch would also create jobs for Nigeria's teeming unemployed population and boost economic activities in the country.
