First shipment of Panasonic 3D TVs has sold out Stateside in a week, while Marks & Spencer confirms it will start selling Sony 3D TVs in the UK from June 21st

Panasonic says it has sold out of 3D TVs in their first week on sale in America. But it has not said how many of the 3D models were available in the first shipment.

The initial success in the US has raised optimism that the technology that helped Avatar break box office records could soon extend to living rooms and help boost the profits of the TV manufacturers, who have struggled with increasingly slim margins on standard flatscreen TVs as prices have dropped.

Blockbuster 3D movies and sports event such as the 2010 World Cup are expected to drive demand for 3D sets, and today Sky has confirmed that its 3D TV channel will launch on April 3rd.

Virgin Media is also developing 3D TV, which it will demo at the Ideal Home Show in London this weekend.

Panasonic was the first manufacturer to sell 3D sets in America on March 10th, with a 50in model bundled with a 3D Blu-ray player and a pair of 3D glasses selling for $3000 (£1960).

More after the break

• In a separate development, Marks & Spencer has today confirmed it will sell the Sony Bravia KDL-40LX903 3D TV with two pairs of 3D glasses included for £1999 from June 21st.
