"These record numbers from the opening two weeks of the 2012 Toyota AFL Finals show that more people are watching the game than ever before," Gillon McLachlan, the AFL's chief operating officer, said on Monday.

"With Victoria, New South Wales, Western Australia and South Australia all represented in this year's finals up to the end of the weekend, we've seen significant viewing numbers from right around the country.
