In China, Alibaba and Tencent compete for food delivery to expand access to a fast-growing source of mobile user data, using their chat and wallet super apps to funnel customers to their food delivery apps

In the West, the rivalry is direct between the food delivery apps – Just Eat, Uber Eats, and Deliveroo – and the costs of last-mile delivery dissuade challengers

In the UK, Amazon will change the game if it succeeds in its proposed purchase of a minority stake in Deliveroo, which Uber failed to buy last year. Progress on the merger of Amazon and Deliveroo is suspended by the regulator

Subject to BBC Trust approval, Canvas looks almost certain to launch in spring 2011 after the OFT decided that it did not have the jurisdiction to review Canvas under the merger provisions of the Enterprise Act 2002. The OFT decision does not rule out complaints on other grounds, but the chances of persuading the regulators look very small

The launch of Canvas promises to strengthen significantly the free-to-air digital terrestrial platform, otherwise very limited compared with satellite and cable platforms in terms of bandwidth, but mass adoption poses numerous challenges and it is open to question whether Canvas will ever extend to more than half the DTT base

In the long term, it is hard not to see Canvas as an interim step in the growing convergence between the TV screen and the internet, raising the question of how successfully its PSB TV-centric approach can adapt to the coming challenges of the full blown digital age
