Apple’s subscription TV service has reportedly been delayed until next year due to a lack of progress in licence programming.

Citing people familiar with the matter, Bloomberg reported that negotiations with broadcasters like CBS and Twenty-First Century Fox to licence programming are progressing slowly.

Apple had earlier planned to launch the service in Autumn this year. The lack of content and computer network capacity forced the company to scrap plans for the announcement of the service at an event, which is due to be held in San Francisco on 9 September.

The company still plans to unveil a more powerful version of its Apple TV set-top box at the event.

The people said Apple plans to offer a package of popular channels for $40 a month, which is about half of the average cable bill in the US.

Apple has been working to remake video entertainment for over a decade. It is struggling to find the correct mix of channels at a price of around $40.

The company is working on strengthening its long-term growth outlook and a live TV service will provide it with a new revenue stream.
