Sky TV has introduced a new basic tier TV subscription designed to drive uptake of its 3D channel.

Entertainment Extra + will offer subscribers access to 3D entertainment content such as Galapagos via the linear Sky 3D channel and on-demand service.

3D sports and film content will be blocked for Entertainment Extra + customers – remaining accessible only by the broadcaster’s top tier Sky World subscribers.

The £31.50 per month pack, which launches in April, sits alongside the existing Entertainment and Entertainment Extra packs and also includes access to 45 HD channels.

Currently subscribers to the Entertainment and Entertainment Extra packs, who pay £21.50 and £26.50 per month respectively, must pay an additional £10.25 for access to the HD channels but this will be cut to £5.25 from April.

As part of the changes Sky will move its archive library of shows exclusively onto the new Entertainment Extra + pack.

Sky’s brand director of TV products Luke Bradley-Jones said in a blog post that the new pack was designed to convert SD homes into 3D and HD homes.
