I have just been analysing data on BARB.co.uk. Here are some interesting statistics:
For week ending 21st September 2014, 37.7million people watched Itv SD for 3+ minutes.
For week ending 22nd September 2013, 39.9million people watched Itv SD for 3+ minutes.
That is a drop of 6pct for Itv in real terms. This is in line with lots of the c10pct yoy ratings declines Itv programs have been suffering recently. Incidentally Itv+1 was down in weekly reach too.
On the other hand, BBC1's weekly reach increased from 45.5million in 2013 to 45.8million in 2014. So the weekly reach gap between BBC One and Itv is getting wider, for that week about 8.1million more viewers watched BBC1 at least for 3mins compared to Itv. That is a fantastic advantage to have in terms of attracting viewing figures, when your general base level is about 21pct higher than your main rival channel!
That means instantly for any given new show being launched on BBC One, it is about 21pct more likely to hit a certain number [4million for example] compared to if that same show launched on Itv in the same slot against the same kind of competition/promotion and same kind of lead-in.
Incidentally, if we go back just 4 years for the same week... Itv weekly reach was 42.6million while BBC One was 47.2million. So BBC One's reach has declined 3pct, Itv SD's has gone down a massive 12pct in 4 years.
