Ping (Apple)

Apple's music social network was announced as "Facebook meets Twitter meets music" in 2010 — Apple failed to secure Facebook integration, users had to find friends by email, nobody used it, killed September 2012

Fatal mistake: Ping was Apple's music social network built into iTunes — follow artists, share music, see what friends were listening to. Announced September 2010 by Steve Jobs as "Facebook meets Twitter meets music." Apple failed to secure a Facebook integration deal, launching without Facebook's social graph. Users had to manually find friends by email. No one used it. Apple quietly killed Ping in September 2012.
