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.

There has been no shortage of attention paid to declining TV viewing over recent years, but much of it focuses on overall viewing time rather than advertising delivery.

This is to overlook the engine driving most of the UK’s television industry. Commercial impact delivery has held up well relative to overall viewing, and is strong for certain key demographics.

Nonetheless there are generational and behavioural changes afoot which are exerting downward pressures on impacts, especially for younger audiences. An archipelago of Love Islands is needed (Stranger Things have happened).
 

Linear TV's decline continued into 2018, with an overall drop of 3% across the first 12 weeks YOY. However, overall TV set usage remained flat at 4 hours/day, as time spent on unmatched activities—which includes Netflix, Amazon and YouTube—continues to rise.

Within the ever-shrinking pie of consolidated viewing to the TV set, share of viewing (SOV) to the ten largest channels remains broadly flat. Across the whole of 2017 and the start of 2018 the best performer has been ITV (main channel).

Several big-name digital channels are showing surprising signs of recent decline, including UKTV’s Drama and Viacom’s 5USA. It is too early to tell if these declines are a blip or a trend. However, they reflect stalling growth from the long tail of digital channels in aggregate. 

A change of control clause triggered by Discovery’s takeover of Scripps will grant BBC Worldwide the option to acquire the 50% of UKTV that it does not already own

With a possible price in the vicinity of the £339 million paid by Scripps in 2011 it is by no means certain the BBCW could proceed alone—so a new, minority partner may well be necessary

Discovery, on the other hand, may be keen to acquire full ownership of UKTV, while retaining a licensing arrangement for the BBC’s content. A channel portfolio containing the best of Discovery, Scripps and UKTV content built on UKTV’s strong EPG positions would transform Discovery in the UK
