Hmm.. I find it hard to beleive that the same people who can afford 250 rand a year for a TV license will be unable to provide a subsidised amount toward a set top box.
Realistically, there is no real option, but to provide the boxes to licence holders at a once off cost or a annual/monthly subscription addition (if you cant afford to buy it outright) over the period of 3 years or similar .. that would mean if the government didnt subsidise at all it would be able to be paid after about 3 years at double the annual tv license fee (ie 250 rand per year or 20 rand per month).
Assuming a government subsidy for poorest of the poor of maybe 15 rand per month this would allow the license holder to pay R8-10 rand per month and still pay it off in about 3 years.
Both options will mean it would be possible to roll out in 3 years TOPS ..
But realistically, the government / SABC dont give a hoot about whether the STB recipients have TV licences or not, they are just mortified at the thought of the propaganda machine being unnaccessible to the millions of unlicensed television viewers, who they are hoping to give STB's to for free ....
