The proof is in the pudding - that is, the shows' ratings.
After AM's launch yesterday to mixed reviews, the numbers are in - and they show that TVNZ 1's Breakfast remained in the top spot for viewership all morning.
According to figures from Nielsen, Breakfast sat 86 per cent higher for audiences aged 5 and over, while in the key 25-54 age group, they were 115 per cent higher than AM.
Breakfast's average audience yesterday was 112,200 in the 5 and over age group and 39,000 for those aged 25-54.
Meanwhile, AM netted an average audience of 60,400 for those 5 and over and 18,200 in the 25-54 age range.
A Discovery spokesperson said two days in, the AM team has received "a lot of encouraging feedback".
"And we know we have the right ingredients to find and build our audience over time."
