I'm not talking about pre-album tours.
Fifth Harmony, the group in its entirety, had a presence on the internet. They teamed up with a YouTube channel (that wasn't popular until 5H started working with them) and started showcasing themselves through a variety of clips before their first album came out. Doing that gained them some dedicated fans. Beyond that, they were very active throughout social media individually. They were beautiful and had infectious personalities so it was easy to gravitate toward them.
Can't say the same for June's.
They're not even signed and quite frankly, they don't deserve to be. Like I said, nothing really stands out about any girl. Why should they be offered a chance to have a machine push them into superstardom when there's nothing to... push?
