The third-season premiere of The Hills is doing big things on all platforms for MTV Canada – which has also started sending its spin-off, The Hills After Show, to MTV viewers in the US.

Last Monday’s The Hills (10 pm ET/PT) delivered MTV Canada’s highest season premiere audience on record since the net’s March 2006 launch. The show also broke online records. Half a million video streams were ordered up at MTV.ca on the night of the premiere – about 200,000 for the premiere ep alone – along with 30,000 streams of The Hills After Show (10:30 pm ET/PT). The net is also making full eps and highlights from the show available on Bell Mobility phones.

The season premiere marked the first time The Hills After Show, featuring Canuck hosts Dan Levy and Jessi Cruickshank (pictured), was broadcast online in the US. Monday night was the show’s first airing on MTV US’s TV broadcast sked.

The Hills is sponsored by Dove’s CampaignforRealBeauty.ca, both on-air and online.
