The 'IU Effect' is becoming an issue among the internet users.

Today, one online community forum made a post under, 'The great IU, collects $20,000 within 2 minutes'.

The internet user who posted this had commented, "IU that came out in 'New Life To Children', she was singing a children's song but look at the money collected! It was $280 in the beginning of the song, and as soon as the song it went up to $20,000."

The internet user continued, "Then it reached $23,000 as the song was ending. The song was a children's song so it was not even 2 minutes. Does that mean if she sang 'Good Day', it would have passed $100,000?"

Internet users who saw this commented, "That's so crazy", "IU is the best", and "IU effect, so crazy."
