Another bugbear is the way the volume leaps when the adverts start.

I keep on reading this - but don't notice it most of the time. Of course
it could depend on the channel you're watching.

I've seen this explained as the programme and adverts having the same
maximum volume (of course) but the programmes having a wider dynamic
range than the ads. The average volume of the ads is higher, closer to
the maximum, than that of programmes. Of course, if a programme is
relatively quiet just before the ads the contrast will be noticeable.

Advertisers want "punch". So, they use compression to bring all
levels close to that limit. Same technique as is used on many rock
music recordings. It's extensively discussed on music/recording
forums. Experts deprecate it, but the market seems to want it.

(Before we go off on a red-herring chase, note that "compression" can
mean doing two quite different things to audio. Reducing file size by
making e.g. an MP3 is not what we're talking about.)

A commercial with no sound at all might attract attention. Suddenly the
TV goes unexpectedly quiet so people look at it and see the ad.

Not much on TV does :-) Particularly if deaf AND blind.

I must be due for an eye-test. I initially read that as "compassion"!

So does pretty well everything on TV - and has done for many a year.

There could be a storyline about a character selecting a TV and having

Then there are cars, washing machines, kettles - from various suppliers,
and so on. the possibilities are endless.

I'm surprised no one has mentioned the early 1960s ATV programme, Jim's
Inn.

The ITA put a stop to it, but it was indeed a TV series with product
placement built in.

My age was in single digits, but I do remember a magasine programme
in the Winter Hill area so it might have been Jims Inn, but I don't remember
it being set in a Pub, it was more like this.

I even remember a couple of products advertised,
Sets of building bricks, like Lego but made of rubber.
A shed made by Kencast, called the Ken-Den.

Thank's Charles!

About the same time I did get my hands on what was left of my Uncles
Bayko set, but my interest a few years later was with Airfix Betta Bilda.
I could not understand the obsession with the over-priced and in some
ways inferior Lego.
