MTV Networks International (MTVNI) has plans to significantly expand its high definition services across brands through next year with the launch of new channels and programming.

In doing so, Nickelodeon HD will launch as a 24-hour ad-supported simulcast channel in the UK on Sky starting October 5, which follows on the UK launch of Comedy Central HD earlier this summer. MTVNI will invest in additional HD services with the introduction of an international Nickelodeon HD channel in 2011 in markets such as Poland, Russia, Israel and Brazil.

Nickelodeon HD in will be available to all Sky HD customers that currently take the Kids pack as part of their SD subscription package. Additional carriage deals will be announced soon.

MTVNHD will continue to expand distribution and is expected to be available in 30 countries across four continents by the end of this year.
