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 UK lockdown since mid-March has boosted TV time to levels not seen since 2014, with broadcast TV and online video each growing by nearly 40 minutes/person/day.

While trends vary significantly by demographic, news consumption has been a common catalyst for linear TV’s growth, benefitting the BBC above all. Although Sky News has also flourished, Sky’s portfolio has been seriously impacted by the lack of live sport.

2019 extended many of the long-running trends of the last decade, but, notably, online video’s growth rate appeared to slow among youngsters, in contrast to older demographics. 35-54-year-olds watching more VOD will have significant implications for linear broadcasters down the line.
