Fun facts
This format was initially only in black-and-white, but color versions were developed later on
Despite originating with the 1/2" CV, this format became associated with the portable recording device (known as the PortaPak), which gave birth to the age of electronic news gathering
This format's success can be attributed to it having been developed as a shared, non- proprietary standardized format that could be developed and manufactured by different companies
"...which gave birth to the age of electronic news gathering (ENG). Prior to the use of this man-on-the-street recording device television stations used film cameras to record events outside of the studio, which required film developing time. Imagine the reporter in the field, asking questions into a handheld microphone, then quickly holding the mic out to record the response of the interview subject. There is only one mono channel of audio for 1/2" open reel. When listened to with headphones you'll only hear audio in the left channel." - J. Jay
