I'm well aware of it's origin... I have had some of the first RCA radios that used it as a phonograph connector. But calling an RCA jack a phono jack with video gear rubs me the wrong way.... It's like calling records "vinyls", or using a DVR to record a news broadcast and saying you "filmed the evening news"...
