In June 2007, YouTube began trials of a system for automatic detection of uploaded videos that infringe copyright. Google CEO Eric Schmidt regarded this system as necessary for resolving lawsuits such as the one from Viacom, which alleged that YouTube profited from content that it did not have the right to distribute. The system, which was initially called "Video Identification" and later became known as Content ID, creates an ID File for copyrighted audio and video material, and stores it in a database. When a video is uploaded, it is checked against the database, and flags the video as a copyright violation if a match is found. When this occurs, the content owner has the choice of blocking the video to make it unviewable, tracking the viewing statistics of the video, or adding advertisements to the video. By 2010, YouTube had "already invested tens of millions of dollars in this technology". In 2011, YouTube described Content ID as "very accurate in finding uploads that look similar to reference files that are of sufficient length and quality to generate an effective ID File". By 2012, Content ID accounted for over a third of the monetized views on YouTube.
On Thursday, the Senate voted unanimously to blame Crown Prince Mohammed bin Salman for the murder of the Saudi journalist Jamal Khashoggi, and 56 members—a clear majority—-cast votes to end U.S. support for the Saudi-led war effort in Yemen. The rebuke was followed shortly afterward by a revelation about the Defense Department’s refueling of that bombing campaign: According to the Pentagon, the department had somehow failed to bill the Saudis and the Emiratis for at least $331 million in fuel and servicing costs. The Saudis, it appears, never directly paid the U.S. a penny.
Pakistan was tense on Thursday as countrywide protests against the acquittal of a Christian woman sentenced to death for committing blasphemy entered the second day despite Prime Minister Imran Khan's warning to defiant hardliners. Asia Bibi, a 47-year-old mother of four, was convicted in 2010 after being accused of insulting Islam in a row with her neighbours.
