In the UK, carriage on Sky Q will give the new service the opportunity to prove its worth to viewers. Without integration with the UK's biggest pay-TV platform, growing scale is difficult for nascent DTC services.

Elsewhere in Europe, Discovery seeks to bundle too. Unlike the US, where the company has a single model—basic cable—in Europe it operates both free-to-air and pay channels, and it also owns Eurosport.

Ultimate success will come down to whether Discovery's "real life content" is essential and defensible. Generally there is little evidence of people taking services that are not broad, while the barriers to entry for competitors wishing to commission "real life content" are lower than other genres.

The Government appears set on reducing the scale and scope of the BBC by dismantling the licence fee, and in its place pushing for subscription or making payment voluntary, without any evidence of the likely impact.

DTT – the UK’s largest TV platform – has no conditional access capability, and so implementation would require another costly and long-term switchover.

A voluntary licence fee would inevitably lead to a huge reduction in income. If just those on income-related benefits were not to pay, the shortfall would be over £500 million – in addition to the £250 million the BBC will be funding for over-75s receiving Pension Credit.
