[Neil Jones]

Not sure if this warrants its own thread but am I right in thinking there is a rule surrounding ad break bumpers being too similar to the surrounding programme (for want of a better phrasing)? For example, an intro from This Morning in 1995 featuring a BT sponsorship:

And the intro of 2010's The Krypton Factor featuring a Sage sponsorship:

There was a period in the 90s where sponsorships became effectively part of the programme and they were integrated. This causes problems years down the line when those programmes are repeated.

Big thread on the blue place about it:

This example from CiTV's Tellytots in late 1990s/early 200s was probably the logical conclusion, as the sponsorship is on the exact same shape as the CiTV logo of the time and would have run straight into the strand:

By 2010 and Krypton Factor the lines of distinction had been blurred, and after all these days you have sponsorship bumpers featuring (for example) Chasers that appear during episodes of The Chase... that was a big no no 30 years ago. I remember Channel 5 got in trouble because somebody who appeared on one of their programmes also happened to appear in an advert break during that programme and the ITC said not supposed to let that happen, though I suspect regulator decisions aren't based on precedents.
