“Ping ping ping ping ping — ping ping ping (ping ping ping)”.
Ping is a social network for music which was previously built in to Apple’s iTunes software. Ping allowed users to follow artists and read postings by friends and artists. Ping was launched in September 2010, but it failed to gain traction amid problems with Facebook integration and an unsuccessful attempt at collaboration with Twitter. Apple officially shut down Ping on September 30, 2012.
