In the early 1970s, the music industry was transformed by the arrival of a practical solution to mobile music—the 8-track player. The world embraced this technology, which infected car stereos, home entertainment systems, portable players and lifestyles. While transformational, this technology soon was replaced by the cassette, followed by CDs and audio DVDs until Apple came out with the iPod—another game-changing technology. The market has created many forms of iPod docking stations for cars, clock radios, entertainment systems, airplane seats, pillows and every possible application. Uses include photos, FM radio, podcasts, videoconferencing and Wi-Fi. This technology is significantly smaller, faster, more comprehensive, more capable and inherently more user-friendly than its 8-track progenitor. The same lessons from this progression can be applied to command, control, communications, computers and intelligence (C4I) and government information technology.
