Input: Read this: On October 9, 2006 at 6:00 a.m., the network switched to a 24-hour schedule, becoming one of the last major English-language broadcasters to transition to such a schedule. Most CBC-owned stations previously signed off the air during the early morning hours (typically from 1:00 a.m. to 6:00 a.m.). Instead of the infomercials aired by most private stations, or a simulcast of CBC News Network in the style of BBC One's nightly simulcast of BBC News Channel, the CBC uses the time to air repeats, including local news, primetime series, movies and other programming from the CBC library. Its French counterpart, Ici Radio-Canada Tele, still signs off every night.

Input: Read this: With his third album, Graduation (2007), West moved away from the sound of his previous releases and towards a more atmospheric, rock-tinged, electronic-influenced soundscape. The musical evolution arose from him listening to music genres encompassing European Britpop and Euro-disco, American alternative and indie-rock, and his native Chicago house. Towards this end, West retracted much of the live instrumentation that characterized his previous album and replaced it with heavy, gothic synthesizers, distorted synth-chords, rave stabs, house beats, electro-disco rhythms, and a wide array of modulated electronic noises and digital audio-effects. In addition, West drew musical inspiration from arena rock bands such as The Rolling Stones, U2, and Led Zeppelin in terms of melody and chord progression.
