Another big night for Nine – The Block Glasshouse (1st – 1,425,000) thumps all comers, and while Big Brother (7th – 924,000) slides just below the million it still takes the 8:30pm timeslot with ease. Bringing Sexy Back (18th – 617,000) slumps and surely must now be considered a failure for Seven while Ten’s best – Family Feud (15th – 644,000) – beats it.
