The Glenn Dyer breakdown: It was tennis on Seven versus Nine’s The Big Bang Theory, and the latter won — for at least half an hour last night. Although The Big Bang Theory was not up against Lleyton Hewitt, who played later in the night and gave more than  a million Australians an early morning bed time.

Seven’s tennis audiences won’t be so strong now that Hewitt, the last Australian in the Open, has gone. Hewitt played late, around 10.30pm onwards, and attracted more than 1.3 million people in the five metro markets. After two nights, Seven has already won the week, adding to last week’s big victory.

The Biggest Loser‘s 2012 launch averaged just 897,000 viewers from 7pm to 8pm because of the tennis and the fresh The Big Bang Theory episode on Nine. When ratings really start, The Biggest Loser will find the going tough, especially with Seven stripping My Kitchen Rules for an hour from 7.30pm four nights a week.

Tonight: More tennis on Seven from 7.30pm, Nigella Kitchen on the ABC at 8pm. Don’t forget the Fourth cricket Test against India is in Adelaide this afternoon. Ten repeats Young Talent Time, New Girl and Homeland tonight from 8pm, in case you missed them on Sunday night. Lucky viewers. That’s after The Biggest Loser at 7pm.
