Mega will be the successor to Megaupload which was shut down by United States authorities after Dotcom was controversially arrested on copyright and racketeering charges last year.
Megabox is a sister service that will let musicians sell music to the public online. Dotcom has indicated it will undercut traditional intermediaries such as record labels by allowing artists to retain about 90 per cent of the income their music generates.
An optional software application, Megakey, would let internet users access Megabox for free while still allowing musicians to be paid. Once downloaded, it would replace at least some advertisements on any websites internet users surfed to with ads served up by Mega, thereby eating into other businesses' online revenues.
Some internet experts believe that could embroil Dotcom in fresh copyright disputes with rival online publishers.
