Mining Unmatched Viewing

(And using it to shine a light on changing viewing habits)

A case study by digital.i analytics

July 2017

Unmatched Viewing:

A resource for understanding

changing viewing habits?

Yes, (sort-of).

It's a truth self evident that the way in which we engage with our

favourite TV shows has changed over the last few years.

Undoubtedly this has been driven by the arrival, and success of new

breeds of SVOD services into the market. Thanks to their deep pockets

and savvy content strategies these platforms have gained an incredible

amount of market share in a relatively short period time. It’s certainly

hard to ignore the fact that 57% of UK 16-24's and 39% of 25-34’s now

come into an SVOD service at least once a week 1 .

Another chapter in this story of changing audience behaviour is to do

with how and where we watch our favourite programmes. Audiences

are now increasingly comfortable viewing content via tablets and other

internet enabled devices. As of 2016, 34% of adults BVOD viewing and

35% of their SVOD viewing was spent viewing content on PC’s, tablets

and smartphones. For 16-24’s this is even higher at 51% and 52% 2

(with evidence that this has and will continue to grow in 2017).

Furthermore, unemployment levels among young people have been

reducing significantly since 2012. The amount of young people in full

time employment or education in 2016 resembles that of prerecession

levels in 2007 3 – surely this must create a less available, yet

perhaps more commercially attractive audience?

With these developments and many more putting pressure on the

industry, understanding how as audiences we interact with our screens

has never been more important.

In usual fashion BARB is responding well to the changing market,

working hard to maintain the high level of trust agencies, broadcasters

and more place in the JIC. Most recently this has manifested in the

announcement of new screen time files which will provide accurate

information into the aggregated levels of (you guessed it!) screen time.

Longer term, we’re looking forward to Project Dovetail which will

provide standardised, census level measurement of BVOD and online

viewing on devices such as tablets and PC's.

However a time in which we are able to say with relative confidence

how many people watched the new season or House of Cards or how

viewers distribute their time across different services and channels is

quite likely some way off. Technically speaking, the infrastructure is in

place for BARB to analyse viewing from OTT services but it requires the

cooperation of these providers to supply audio references for its

content libraries (and no word on this yet).

In the meantime, analysis of ‘unmatched viewing’ helps us feel around

the edge of what is going on in our digital day. Of course, bodies such

as Ofcom and Thinkbox approach this subject with regularity,

implementing various primary studies that provide phenomenal

understanding and insights into these issues.

However, analysing these new developments within BARB’s framework

is crucial. It allows us to further our understanding of screen behaviour

within the context of linear viewing, while using a standardised


Unmatched Activity is an umbrella, “catch all” comprised of essentially

anything that BARB cannot identify. It includes (but is not limited to);

paid for and free VOD services, older content on TV catch up services,

use of games consoles, DVD’s and more (see next page 3 for a detailed

breakdown of what unmatched viewing consists of).

While we’re unable to currently dissect unmatched viewing into these

components (although we are working on a interim solution to this,

please go to page 8 for more information) we are able to analyse it

with the same level of rigour and detail that we do normal TV viewing.

Within this document we've done just that; aiming to provide some

useful stats and insights for your viewing pleasure as well as clearing up

some of the confusion that exists in understanding exactly what

unmatched viewing is.

Not only that but using a novel proprietary segmentation methodology

and by mining respondent level viewing data, we’ve broken unmatched

viewers by their weight of viewing. This has revealed some interesting

findings that are well worth a look (see page 4-6).

Lastly, with some rather grand developments going on at Digital.i, we

wanted to take a moment to reach out to our clients, friends and

contacts to showcase some of things that we are working on, and what

you can expect from us in the future.

We hope you enjoy reading!

What is



Audio matching

Unmatched Viewing

To understand what unmatched viewing consists of, it is necessary to

understand that BARB uses audio matching to identify what is being

watched on a screen at any given time. This is a complex process but it

fundamentally all comes down to sound.

The panel meters present in 5,100 homes take samples of the sound

being broadcast and convert these to “fingerprints” that can then be

matched against a reference library of content supplied by content


Using this process, BARB is able to identify who is watching what -

generating the gold standard figures broadcasters, agencies and

bureau's analyse every day. This includes 1 :

Viewing via TV sets to content broadcast in the past 28 days by

BARB-reported channels (regardless of whether it is viewed live,

via a recording, or from a catch-up service);

• The same types of viewing to non-BARB reported channels where

BARB hold an audio reference for the channel, or where the

channel is viewed via the Sky platform. In practice the only non-

BARB reported channels BARB hold references for are some of

the larger DTT channels;

Viewing to programmes premiered or available on BBC iPlayer,

where the BBC has provided an audio reference;

Any other use of the TV set, which fundamentally BARB does not hold

an audio reference for would be classed as unmatched viewing.

This would include:

Viewing to any channel outside the Sky platform for

which BARB does not hold an audio reference

• On-demand content for which BARB does not hold

an audio reference

• Gaming

• DVD playback

• In some cases EPG (depending on the behaviour of

the audio – often the channel audio will remain,

with or without a reduced size picture)

• User generated content (wedding videos, etc)

• Other devices that may be used on the TV such as

security cameras, Raspberry Pi, etc.

1 ”Viewing” to radio stations is also measured as well a few miscellaneous uses for the Sky box such as

(interactive menus). For a full breakdown what itemised please contact us or BARB directly.

How big is unmatched viewing?

In 2016 time spent with unmatched

forms of activity represents 14% of all

screen time in the UK - up from 11%

in 2014.

Among 16-24’s, unmatched is 31%

of screen time – up from 21% in 2014.

Inclusion of unmatched

viewing, neutralises the decline

observed in linear viewing.

While consumption of linear forms of TV may be

declining, total use of the television set is NOT decreasing.

What’s apparent, from even a cursory look at the data, is

that the TV still remains a central hub within the average

home; even if audiences are becoming increasingly

confident accessing and consuming content across

multiple platforms. However, live TV still dominates.

The proportion of screen time that BARB are reporting as

unmatched is increasing. However, linear TV remains the

go-to destination for the majority of audiences.

Younger viewers spend the most time with unmatched

forms of content and they have also experienced the most

significant increases since 2013.

For 16-24’s, unmatched viewing

is now larger than all of the

terrestrials combined.

Unsurprisingly, these shifts are most profound among the

UK’s youngest audiences. For 16-24’s unmatched viewing

represents 31% of their total screen time – but put

differently, for this demographic unmatched activity

achieves a higher share of viewing than the entire

terrestrial portfolio!

31% of unmatched is delivered to the screen by a games

console, 28% by a dedicated TV service (Sky, Virgin,

Freeview etc.) and 27% by the TV set itself (integrated

tuner/smart TV apps).

What we find interesting is that Virgin services makes up

10% of all unmatched and Sky only 6% (compared to 14%

and 36% for Total TV).

Sky, unlike Virgin, does not allow Netflix or Amazon Prime

Apps within its service – perhaps what we’re seeing here is

viewing on SVOD services? (This would need more work to

be validated however).

A new method to more effectively analyse viewer cohorts

Traditional forms of segmenting TV audience may break down audiences into

cohorts of equal size based on their levels of viewing. However this approach has

one relatively problematic side-effect. With TV viewing, there are a small number

of viewers who watch a lot of content, and then a large proportion of panel

members who watch significantly less. The traditional form of audience

segmentation therefore has a tendency to collate the heaviest viewers alongside

those with completely different viewing behaviour. In this sense a panel member

who views 10 hours a day, could be grouped alongside a panellist who views 2

hours a day . Is this a true segmentation?

We’ve come up with a new methodology which groups people together more

accurately based on their consumption behaviour.

It works by splitting audiences based on their equal contribution to daily viewing

rather than equal contribution in terms of respondent volume. This is done by

ranking all panel members on their average daily viewing behaviour and

segmenting them in terms of a 20% contribution to all average daily mins (see

right, which is based on total unmatched viewing).

We are able to do this through the use of our specially designed, bespoke piece

of software which analyses respondent level data from Database 1. We can do

this for any channel, demographic or period (going back as far as 2014).

Ave Daily Hours (Unmatched Viewing 3 ) x panellist, 2016











Ave Daily Hours x Unmatched Viewing Cohort 3 , 2016

For all but the very heaviest viewers,

Linear TV still remains the go-to

destination for viewing.

Using the above method of audience segmentation we have

analysed how audiences consume unmatched viewing.

What it has revealed is that the very heaviest viewers tend to

supplement their levels of live TV viewing as opposed to replacing

it with unmatched forms of content.

Final Thoughts…

The importance that unmatched viewing represents as a resource for furthering our understanding of

the TV market and its audience shouldn’t be ignored.

While the industry (and indeed many of our clients) do analyse unmatched viewing to some extent, we

feel that there needs to be a greater impetus to examine unmatched viewing on a more frequent

basis; whether that be forensically in detailed analytics projects or adding it to regular tracking in preexisting


Clearly it has it’s limitations but we should aim to plunder it as much as possible – who knows what

gems of insight lurk within?

Some of our thoughts on how to take this further….

i. Beyond analysis of standard demographics are there any emergent segmentations to

the audience of unmatched viewing?




How does this differ by different household dimensions (such as region, platform

ownership, size, life stage etc.)?

At what times do viewers tend to spend time with unmatched forms of content?

Conversely, at what points of linear TV schedules more resilient to this type of viewing?

Are there any clear relationships between the viewing of unmatched content and

different channels and/or brands?

v. Strategically, what can be done to mitigate against the negative effects of unmatched





At a panel member level, is there anything that can be learned from analysing journeys

of audiences between linear TV and unmatched content?

Is there any evidence that big launches on OTT services affect viewing/can these even

be perceived?

What can we expect from the future?

Start a conversation!

We would love to hear your personal thoughts on this – please get in touch!

Some exciting things to come!

New digital.i

We’ve just undergone a corporate re-brand and those of you that are eagle eyed will have already spotted our new

logo throughout this report.

We are arranging a launch event in late October to officially unveil the new Digital.i - invites will be issued soon!

Segmentation Methodology

We have developed our own bespoke piece of software that allows us to analyse respondent-level viewing data. Using

this tool we have modelled a brand new, innovative segmentation methodology that allows us to create more reliable


We have uncovered crucial insights for major broadcasters by segmenting audiences using this method. More recently

we have been further developing this methodology to better understand respondent-level volatility and what impact

this has on channel viewing. We have some initial findings which suggest the importance of more effectively targeting

inconsistent viewers.

Unmatched Attribution Methodology

We are currently developing a model that uses a variety of sources to breakdown what unmatched viewing consists of.

The main purpose of this is to provide estimates on the level of viewing to on demand services such as Netflix and

Amazon Prime and we hope, this will ultimately shed more light on the way in which the TV set as a whole is being

used. These estimates are of crucial importance considering that data on these SVOD services is relatively scarce, and

delivery of project dovetail has been pushed back to March 2018.
