[Check if an Ad will be shown/is booked for a specific zone]

Hi,

on a customer Website I need to show the latest three news articles, but if an ad is booked for a specific zone I only display two news articles.

Means:
If no ad is booked:

article 1 | article 2 | article 3

 

if an ad is booked:

article 1 | ad for this zone | article 3

 

Can I somehow find out if an ad would be shown on this zone? Depending on this I'd display different news articles.

 

Thanks in advance,

Michael
