History of submarines few years before the US, and paralleled subsequent US development in this area. In the 1950s, nuclear power partially replaced diesel-electric propulsion. The sailing of the first nuclear-powered submarine, the USN ""Nautilus"" in 1955 was soon followed by similar British, French and Russian boats. Equipment was also developed to extract oxygen from sea water. These two innovations, together with inertial navigation systems, gave submarines the ability to remain submerged for weeks or months, and enabled previously impossible voyages such as the crossing of the North Pole beneath the Arctic ice cap by the USS "Nautilus" in 1958. Most of the
Road to the North Pole described the episode as "Christmas comedy gold", praising the 'Christmastime is Killing Us' song and Boreanaz's cameo. The Parents Television Council, a conservative campaigning critic of Seth MacFarlane works, named "Family Guy" its "Worst TV Show of the Week" for "Road to the North Pole" for the week ending on December 17, 2010. It got this rating due to sexual content and excessive violent scenes including the scene in which Stewie beats a man to death with a baseball bat, and the scenes featuring Seth MacFarlane's father, Ron, while also stating, "Forget naughty or nice. This show was simply nauseating."
