The song has also achieved commercial success by topping charts in the United States and Canada as well as reaching the top ten in many countries around the world, including Australia, Finland, Norway, Sweden and the United Kingdom. In the United States, “3” debuted at number one in the Billboard Hot 100, becoming the first song to debut at the top position in over three years.

The music video was filmed on October 5 and October 6, 2009 in Los Angeles, California, directed by Diane Martel and choreographed by Tone & Rich. Fashion stylist GK Reid worked closely with Spears to design the fashion. On October 15, 2009, images of the video were released. A countdown, including images and video previews, was announced on her official website and the release date was revealed to be on October 30, 2009. When asked about the video, Diane Martel said,

“I think it’s her next sexy video. It’s a very simple video for her – I don’t think you’ve seen her this much under a magnifying glass. Everything’s really strong and playful. We collaborated on the wardrobe and had meetings about hair and makeup people, we talked a lot on the phone and met Tone and Rich — two of the best choreographers. [..] [Spears]’ so sweet and funny and so normal and down to earth. It’s really fun as a director to see her in front of the camera. She’s so creative with this stuff. The video is very simple, it’s very, very minimal. So it’s her, her, her. And she’s totally engaging every second. She really knows how to work with a camera and move. I was really impressed, and I have worked almost with every female artist in the business”.
