TVNZ is rebranding its digital channel TVNZ6 to a youth-focused channel called U. The new-look channel will launch on March 13 and target New Zealand youth aged 15-24. The broadcaster has formed a partnership with social networking site Facebook, in a bid for integration and closer relationships with viewers. U will feature a hosted block of content from 4pm to 7pm daily, driven by a live Facebook application. See more at:
