ITV and Channel 4 have asked the regulatory authorities to review the case for legislation that would for the first time allow the commercial PSBs to charge carriage fees for their main free-to-air channels on the pay-TV platforms

To this end, ITV has presented a detailed analysis showing the great contribution to the US creative economy due to the introduction of Retransmission Consent Compensation for free-to-air broadcasters in the US, but without setting this against the very different market structure in the UK, where the commercial PSBs enjoy significant privileges

Any change to UK rules will require primary legislation and is not expected until after the May 2015 General Election. Should action be taken, the choice appears to lie between regulation (adding “must carry” rules) and deregulation of commercial PSB privileges, where the end result might not be what the PSBs wished

Older adults have always watched more TV than younger adults, and even more TV news. The gap has widened over the last five years following the rapid rise in online news consumption via websites or apps among the under 35s, where online is now used as widely as TV for getting news.

Recently published survey data by Ofcom (UK) and Reuters (10 countries) highlight the importance of online as a tool for accessing breaking news, whether search engines, news websites or social networks, along with an expanding field of news content.

Online, with its emphasis on reading rather than watching news stories is no direct substitute for TV. The BBC is by a large margin the most widely accessed online source in the UK, while the challenge for the other TV news providers is to develop commercial models that successfully integrate broadcast with online.

The commercial non-PSB sector saw strong growth in share of total TV viewing of close to 40% as the multichannel TV homes universe doubled in the 10 years between the launch of Freeview in October 2002 and completion of digital switchover in October 2012, and even higher 50% growth in SOCI (share of commercial impact) thanks to the higher commercial airtime quotas of the non-main PSB channels

Even during the growth years, non-PSB channels that were present in 2003 felt a squeeze on viewing share and suffered losses as result of numerous channel launches that added to the long tail (Squeeze 1), and strong growth in the PSB families (Squeeze 2), which saw the total PSB share among the Top 25 channels in multichannel TV homes rise from less than 80% to over 90% between January 2003 and January 2014

Today, both the PSB and non- PSB commercial channel groups face the challenge of internet connectivity and increasing population of portable screens (Squeeze 3), and they are experiencing similar rates of decline. Yet, even if overall trends look the same, non-PSB viewing trends show significant variation by channel group and genre, to be explored further in Part 2

The Charter Review of the BBC officially opened with the Culture, Media and Sport Committee’s inquiry into the Future of the BBC asking the question “What should the BBC be for and what should be the purpose of public service broadcasting?” The only obvious answer is that the BBC and public service broadcasting should be for the people of Britain, and the BBC rates highly on different measures of public and audience engagement. The BBC plays an irreplaceable role in the supply of PSB programming that UK audiences appreciate, most importantly news, where the BBC accounts for 70% of TV news time and for 22% of online news time in 2013.
