When did Demi become a Pop Girl?

[POPBOIY]

I think it was honestly with the release of The superior single, Heart Attack 

I also think Unbroken era was the begining of making her a pop girl. Ex: Skyscraper 

What do y'all think?

Tbh I think she was always a pop artist, but if you're talking about when she joined the leagues of our icons, I definitely think it was 'Skyscraper'. That song was annoying and so overplayed but it definitely helped her blow up further than she had before!

Demi was always huge at my country, since La La Land she's a big name here and i remember it being so overplayed  

I guess her international success became bigger and she really got some radio airplay after Unbroken indeed. I don't remember Skyscraper being huge but Give Your Heart a Break definitely had a decent success. From Heart Attack on i guess that's when she got way bigger tho, even though she still flops a bit compared to Ariana, Selena etc.
