Whitney Houston comes back from the grave to kill Seven’s ratings

The second episode of Seven’s celebrity post-mortem series Autopsy helped kill the network’s ratings on Thursday night, with just metro 470,000 viewers tuning in to hear the medical evidence behind singer Whitney Houston’s death.

The audience for the show – which aired at 8.30pm –  was even worse than for the first episode of Autopsy covering Michael jackson’s death which rated 644,000 last week.

The show was 20th for the night, according to preliminary overnight metro ratings from OzTAM.

Ratings across the board are down this week, in part because of networks holding back prime programmig until school holidays are over.
