BT Sport has seen a very clear positive impact from its first year airing the Champions League, with viewing up 60% year-on-year to June. Remarkably, its reach is now not too far off Sky Sports, though it still has some way to go in terms of consistent viewership.

Pay-TV audiences for the 2015/16 tournament were in line with previous years – an impressive feat – but free-to-air disappointed. However, BT should not be too concerned – it has established itself as a worthy pay-TV partner.

While BT’s execution has thus beaten reasonable expectations, BT Sport still carries a heavy net financial cost for BT, with debatable benefits. Yet, whatever the benefits may be, more viewers watching more often must surely help.

Video content is crudely defined. If something is not very short (<10 minutes) then it tends to be considered long-form. But there is a middle ground - one which displays a distinctive combination of characteristics in terms of production, broadcasting and viewing

Mid-form video (between 10 and 20 minutes) has the ability to carry the narrative arcs normally associated with long-form programming, whilst also retaining the snackable and shareable attributes of short-form

The footprint of mid-form is, so far, small. However, it is growing, as its unique qualities, such as excellent ad completion, become more readily recognised

BT will soon for the first time charge the majority of viewers for their own channels with the launch of the BT Sport Pack. The Pack includes BT Sport Europe, exclusive home to UEFA’s European football tournaments from this August, the rights to which BT are paying £299 million a year.

Viewing figures for the big European tournaments are not as high as one might expect given their prominence. Consumer demand for the new channel will also be highly dependent on the success of British teams, notably lacking in recent seasons.

We therefore do not expect a dramatic impact on BT Sport (or BT broadband) subscribers, and the widening losses will put pressure on BT’s margin squeeze test regulation, although they are easily absorbable at BT Group level.
