Google has discontinued its paid video download service which offered users online access to premium videos, mostly television shows.

The free Google Video service will continue to operate under its current beta status.

As part of the shutdown, the company plans to disable all movie files obtained through its 'download to own' and 'download to rent' systems by 15 August.

All videos purchased after 18 July will be refunded in full. Videos purchased before that date will be refunded as credit for Google Checkout, the company's payment service.

The announcement marks the end of a service first launched at the 2006 Consumer Electronics Show. The service required users to download a special Google video player in order to view the videos.

The paid video service was put in a precarious position in October when Google announced a deal to acquire YouTube and then proceeded to make deals with major video producers to serve content free of charge.

In January, Google outlined a new strategy for the two services in which Google Video would be marketed as a video search engine while YouTube would focus on serving and hosting.

Both services are supported by advertising rather than fee- or subscription-based models.

Google does not break the revenues for its paid video service. In 2006, the company reported that 99 per cent of its profits came from advertising revenue, according to a filing with the Securities and Exchange Commission.
