"That advertising was created in Germany" - why not?

[WarsawWill]

It seems to work for "this", so why not for "that"?

Advert/advertisements are nouns, advertising is a verb and wouldnt make sense in this sentence

[WarsawWill]

"advertising" is also an uncountable noun, and is also translated as "reklama". If the speaker is pointing at a variety of advertising material, rather than a single ad, it would just about work here.

Hmm. So in this context, I guess it can work. Added now.

[IanBiddle]

advert not accepted why?

[Jellei]

"advert" is an accepted option, it should have work. Perhaps you made a typo somewhere and the algorithm corrected you to the starred answer, which uses "advertisement".

The result was already written

A screenshot would be helpful, if you encounter the problem again.

[Larry11215]

"ad" should be an accepted option. In the USA no one says advert

[Jellei]

It is.
