EMarker
Launched in the late summer of 1999, the Sony Emarker® was a keyfob sized, battery powered, USB enabled device that allows the user to identify the name and artist information of songs played on local, terrestrial radio stations. The Emarker® user would click the device and enter the radio call letters of the radio station playing the song the listener wanted to identify. Later, the user would 'synchronize' the device with an internet connected computer and the software would gather the information about the song or songs the user was curious about. The Emarker® was widely available both in retail storefronts and on online. [1 Sony described the Emarker as "A neat little gadget that is available now for about $20, the EMK-01 can be put on your keychain. Install the included software on your PC and enter the call letters and frequency for your three favorite radio stations. Then, whenever you hear a song on the radio that you want more information about, simply press the button on the tiny device. When you get back home, plug the eMarker into the USB connected cradle and it will retrieve the song title, artist and other pertinent information and display it on your computer." Sony discontinued the Emarker® service in September of 2001. 2
