The figures cement the huge growth in key demographics driven by Big Brother across all of Seven’s platforms.

“We were confident that Big Brother would deliver massive audiences in the key demos, particularly 25-54s, and the ratings released today confirm it. Big Brother has shifted our audience, being instrumental to us winning all key demos the last seven weeks in a row. It’s also been the foundation of 7plus breaking records, now winning 15 weeks in a row as the top CFTA BVOD service. We’re just getting started and we’ve got plenty more wins to come.”
