Consumer expenditure on recorded music continued its decline in 2014 by about 6% to $18 billion, as purchasing of download-to-own (DTO) albums and singles passed its peak in 2013, adding to the ongoing decline in total sales of CDs that started a decade ago Streaming is now the only growth story left for the industry, and it has a global footprint, being embraced by developed and emerging markets alike, unlike purchasing The US phenomenon of rapidly rising revenues from ad-supported audio streaming services such as Pandora and music video streaming on YouTube is quite unique as other markets currently lack the potential for online advertising

For the second year running, 2014 has seen a steep year-on-year decline in total daily average viewing time, which fell by almost 5%, and was again, as in 2013, greatest among younger age demos, especially among children aged 4-15 where the decline reached double figures

Connectivity and the rapidly growing population of smartphones and tablets appear the main, though not the only, causes of a decline that appears general across the main PSB, PSB family and non-PSB channel groups. The decline nevertheless varies by channel genre, with the more youth oriented, such as Children and Music, feeling the connectivity squeeze the most

Whilst the great majority of non-PSB channels are only available on the pay-TV platforms, the DTT platform provides a significant audience and advertising contribution (ballpark estimate of £150-200 million per annum) to the relatively small group of leading free-to-air non-PSB channels, which are also less constrained in developing their online initiatives than the mixed advertising/subscription non-PSB channels on the pay-TV platforms

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)
