I grew up in Germany and although I moved to another country 18 years ago, I still speak German every day. I did not have much contact with German talk radio for these 18 years. Recently I've started listening to German radio podcasts (WDR 5).
I noticed that when two people talk on the radio, the talk often ends with one person thanking the other for their contribution and the response for the thanks is a "Gerne!"
Is that new? I am totally familiar with "gern geschehen", but just "Gerne!" strikes me as odd.
Person A: Danke, dass du dir die Zeit genommen hast, uns davon zu berichten.
Person B: Gerne.
Is that language change in progress? I definitely never heard that when I still lived in Germany.
