Further sharp year-on-year declines in viewing share by the leading commercial PSB channels, ITV1 and Channel 4, in Q1 2012 run contrary to the general stabilisation of viewing trends as Digital Switchover nears completion

The Channel 4 decline is more easily explained by exceptional factors, while closer examination of NAR trends suggest that ITV Family NAR has performed less well in recent quarters than results releases suggest

Once past Digital Switchover, digital convergence trends appear less of a threat towards the future stability of ITV and Channel 4 family viewing trends than the competitive threat from Sky as it raises its investment in UK programme origination

With the economy drifting sideways, we have set our centre case forecasts at 0-1% average annual growth in TV NAR and assigned a low probability to a repeat of the hyper-cyclical downturn of 2008/9

Comparative international data show a pervasive long term weakness in display advertising trends across the developed world, while emerging markets in Asia, Latin America and Central/Eastern Europe take an increasing share of global budgets

With digital switchover near completion, channel viewing shares across the main commercial groups should stabilise, but internet advertising, especially online video, will exert a negative structural downward pressure on TV NAR over the next three years at least
