Apple has confirmed that its Apple TV device will not be released until mid-March.

The company had promised at the beginning of January that Apple TV would be shipped by the end of February; as the month as progressed, it has become obvious that it wouldn't be.

The devices are expected to be displayed starting on 5 March, but those buyers who have already pre-ordered say that their orders still promise to ship on 28 February.

Apple TV costs $300 in the US, and was first previewed as iTV last autumn. It was officially announced at Macworld Expo in January.

Some analysts believe that Apple TV will contribute around $500 million to Apple's sales this year, as it's expected to be a popular product.

Apple TV is a networked device that will be able to store around 50 hours of TV as well as access media files on the PC.

It offers HDMI, USB2, and 802.11b/g/n connectivity.
