Cross-device identity profiles are used to stitch together fragmenting online ad audiences, but also to enable new links between advertising and marketing, across European markets

This moves value from media itself to understanding each consumer and how they access content and services on proliferating connected devices

By 2020 we predict that 58% of all UK online ad buys by value will make use of high-quality audience IDs, led by the largest advertising platforms but limited by privacy regulation and cost

2016 was yet another year in which we saw big changes in the UK’s video consumption habits amongst the under45s, with little let up in the decline of traditional broadcast linear TV viewing for the younger age groups.

Online video-on-demand services will continue to grow, partly at the expense of traditional TV audiences. We also expect the overall volume of viewing to rise, mainly due to wider production of and access to short-form content.

Despite these changes, conventional broadcasters look to be strong for years to come—we estimate they will still account for 80% of all video viewing in 2026.

Linear television's audience is ageing; with the drop in viewing by younger demographics, consistent viewership by the over 65s has seen them increase their share of total viewing since 2010 from 24% to 31%

The difficulties and efforts to re-engage with the younger cohorts are well documented. But what of the resilient, older group that forms the stable core of the television audience?

Conspicuous attempts are being made to create specific shows targeted at the oldest viewers, but outside of limited categories, creating relevant programming may be more difficult than expected

In the UK, traditional broadcast television's future appears threatened, as technological developments increasingly allow people to access video content on demand, whether on TV sets or other screens, or from traditional broadcasters or online services.

This report examines the extent to which timeshift viewing, by which we mean personal video recorder (PVR) playback and viewing to catch-up services, has bolstered linear TV.

The linear schedule is still very relevant for both consumers and advertisers, maintaining television’s status as an effective mass medium for building brands.

Channel 4's digital diversification strategy is a topic we first considered in 2002. At that time, we urged Channel 4 to husband its resources to meet its public service remit and maintain audiences on its terrestrial service, rather than diversify into new digital satellite channels. If anything, the progress of time has reinforced our conclusion that Channel 4's digital diversification strategy is risky. The risks for Channel 4 are greater than for the BBC, since Channel 4's public service remit is funded by advertising alone

On 27th July the BBC will open access to the iPlayer to UK internet users, en route to a hard launch later this summer. This PC-based application allows the user to download BBC TV content after broadcast to view on the PC for a limited time, and provides a TV-like display on the PC. Delays to the launch will mean the iPlayer enters a field already crowded by other broadcasters, including Channel 4's 4oD service, ITV's broadband portal, Sky Anytime, as well as content aggregators such as Joost and Babelgum (both currently in beta)
