It’s more interesting that none of that is correct!
As far as I can tell the above release refers to the program “Seven News” which is the 6pm coded portion. This is also evidenced by the statement “has won 21 of the 26 weeks so far in Melbourne.” Checking our weekly tally 7 News has only won the 6pm portion of the hour 21 out of 26 weeks.
Also the figures for 10 News are also just for the program coded as 10 News - ie not including 6pm.
So, somewhat deceptive to exclude the 6.30pm portion - it would make the numbers lower and possibly not as convincing a win??
