I skipped a bit too far to the endcap. Didn't notice the credit beforehand. I thought it usually said "presentation" for programmes not made by the company.
"Presentation" was used for imports that were broadcast on the network by each region. So for instance, Home & Away would be An HTV Presentation in Wales, A Carlton Presentation in London etc...
"Programme" meant it was commissioned by a specific ITV company from an indie.
"Production" meant it was produced by a specific ITV company (obvs)
