Technologies for crowdsourced media streaming include a number of mobile computing devices configured to capture media streams and transmit the media streams to a media server. The media server associates the media streams with metadata describing the media streams, including metadata describing an event captured in the media stream. The media server also processes the media streams to generate additional metadata. A number of client computing devices may submit media stream requests to the media server, and the media server contemporaneously streams matching media streams to the client computing devices as the media streams are captured by the mobile computing devices. The client computing devices may transmit feedback information relating to the media stream to the source mobile computing device via the media server. The client computing devices may display the media streams alongside or overlaying other media such as a broadcast media event. Other embodiments are described and claimed.
