Abstract: Methods for implementing shared experiences using mobile computing devices comprise capturing audio waves associated with a media using a built-in microphone of a mobile computing device, the mobile computing device including a processor, a memory, a display screen, a built-in battery to power the mobile computing device, and a built-in communication module to enable wireless communication. A signature is generated from the audio waves captured by the microphone. Based on the signature being recognized as a known signature, the signature and positioning information are transmitted to an audio server using the wireless communication. The positioning information identifies a specific moment in the media that a user of the mobile computing device is listening, the audio server and the mobile computing device connected to a network. Activity information is received from the audio server. The activity information is related to the media and associated with a third party server connected to the network.
