On 16 March 2013, the BBC announced that it would launch BBC News HD, BBC Three HD, BBC Four HD, CBeebies HD and CBBC HD on all digital television platforms which carry HD channels. On Freeview HD (and YouView), BBC Three HD and CBBC HD would use capacity on the BBC's existing HD multiplex covering 98.5% of UK homes; BBC News HD, BBC Four HD and CBeebies HD will use new HD capacity which will cover part of the UK and grow in coverage over time. These high-definition simulcasts are available on the second multiplex, but the second multiplex is only broadcast from selected transmitters, providing around 70% coverage across the whole of the UK.
