Apple is discontinuing its iconic iPod more than 20 years after it released the revolutionary music player.

In a$4, Apple said that the $4 — the only version still being sold — will still be available "while supplies last."

The reason for the iPod's discontinuation is that many of its other products have incorporated the device's portable music streaming function, Apple said.

The news immediately sparked a flurry of nostalgic posts on social media, with users sharing pictures and reminiscing about their favorite iPods collected over the years.

British gaming YouTuber @MrDalekJD tweeted: "Damn... lowkey a little sad to see that Apple has officially discontinued the iPod from today. This thing changed the music game forever. RIP."

Released in 2001 with a scroll wheel, the iPod was the first MP3 player capable of storing 1,000 songs. Besides the iPod and iPod Touch, other versions of the device have included the iPod Mini, iPod Nano, and iPod Shuffle.

Apple has sold around 450 million iPods since the device was launched, the $4, citing information from venture capital firm Loup Ventures.

In the blog post, Greg Joswiak, Apple's senior vice president of worldwide marketing, said that "the spirit of iPod lives on."

"Music has always been part of our core at Apple, and bringing it to hundreds of millions of users in the way iPod did impacted more than just the music industry — it also redefined how music is discovered, listened to, and shared," he said.
