Using a little understood provision of the merger rules, the government has asked Ofcom to take a look at the Sky stake in ITV, just in case the OFT did not come up with the right answer the first time round. As a result of the intervention, Ofcom will decide whether the share purchase reduced the number of separately managed broadcasters in the UK. Since this is almost exactly what the OFT is already doing, it is impossible to see how Ofcom could reach a different conclusion to the OFT. In this sense, the intervention has little point

Vodafone and Orange are planning to share their 3G networks in the UK, and are looking at potentially sharing their 2G networks in due course

H3G has removed roaming charges for customers roaming onto its own overseas networks. While reducing roaming prices can be partially, or even fully, compensated for by elasticity effects, removing them altogether has far more limited direct compensations, especially when consumers are on bundle tariffs

On Wednesday Orange announced a simple new single tariff range for all its new contract users. Although there are some benefits to both consumers and Orange of tariff simplification, the main impact appears to be to increase the price of calls for off-peak users, which is a sensible strategy for Orange and consistent with other tariff increases we have seen recently. Orange may lose customers because of this, but it has helpfully given four weeks warning of the change to the other operators, who may react with changes of their own.

Weak economic growth is usually blamed, but we believe that other forms of communication are substituting for fixed voice calls. Substitution of fixed line calls by calls from mobile phones is increasingly less important. By contrast, our conclusion is that Internet-based communication (email and instant messaging) has recently become a far more important source of competition to fixed line voice calls.

This note discusses the likely obstacles to a successful launch of H3G UK, the most aggressive 3G new entrant in Europe. Our main points:

What does this mean for the media industry? Does the increasing power of media buyers mean further downward pressure on rate cards? We suspect that many of the effects have already been felt, particularly in the European and US TV businesses. In fact, we see a different issue emerging: the explosion in advertising inventory in the last few years, which has resulted in a worldwide glut. This has coincided with what we think may be a permanent reduction in the absolute number of advertisers. As a result, media buyers will continue to obtain better terms, whether in buying as part of a large group or not, but media price deflation may be a feature of the industry for many years to come.

The flow of news about ITV is going from bad to worse. But we think that the market may have misunderstood the real story behind last week's bombshell that ITV viewing has fallen by 25% in a year. This figure could have been predicted from existing data.
