On November 24, 2014, a hacker group which identified itself by the name "Guardians of Peace" leaked a release of confidential data from the film studio Sony Pictures. The data included personal information about Sony Pictures employees and their families, emails between employees, information about executive salaries at the company, copies of then-unreleased Sony films, plans for future Sony films, scripts for certain films, and other information. The perpetrators then employed a variant of the Shamoon wiper malware to erase Sony's computer infrastructure. During the hack, the group demanded that Sony withdraw its then-upcoming film The Interview, a comedy about a plot to assassinate North Korean leader Kim Jong-un, and threatened terrorist attacks at cinemas screening the film. After many major U.S. theater chains opted not to screen The Interview in response to these threats, Sony chose to cancel the film's formal premiere and mainstream release, opting to skip directly to a downloadable digital release followed by a limited theatrical release the next day. United States intelligence officials, after evaluating the software, techniques, and network sources used in the hack, alleged that the attack was sponsored by the government of North Korea, which has since denied all responsibility.

The Cadillac V8, introduced as the Type 51, is a large, luxurious automobile that was introduced in September 1914 by Cadillac as a 1915 model. It was Cadillac's first V8 automobile, replacing the four-cylinder Model 30, and used the all new GM A platform for the entire series shared with all GM division brands using a 122 in (3,099 mm) wheelbase, while a 145 in (3,683 mm) chassis was offered separately to be used for custom coachwork. The Types 53, 55, 57, 59, and 61 were introduced every year through 1923 with yearly improvements until an all new platform was substantially updated and introduced as the V-63. It was built at the Cass Street and Amsterdam Avenue factory in Detroit, with the body provided by a number of coachbuilders, including Fleetwood Metal Body in Fleetwood, Pennsylvania. When GM decided to enter Cadillac as their top level luxury car as an alternative to luxury brands already established, it was a competitor to the all-new Packard Twin Six. The most expensive coachwork option offered from Cadillac for 1915 was the Berline Limousine at US$3,600 ($90,983 in 2019 dollars ). All of these models used a new L-head V8 engine, one of the first V8 engines ever mass-produced and a substantial differentiator for the marque. All bodies were built by Fisher. The Type 51 was also the first left-hand drive Cadillac—all previous models had been right-hand drive, which was continued as an option. Wheelbases varied in those years, with 122 in (3099 mm) at the low end and 145 in (3683 mm) as the longest. The 1916 Type 53 was the first car to use the same control layout as modern automobiles- with the gear lever and hand brake in the middle of the front two seats, a key started ignition, and three pedals for the clutch, brake and throttle in the modern order. This Cadillac was driven by a 77 horsepower V8 engine. The Type 53 designation was used one year only, then each year the designation number would update for each model year. Nine body styles were offered, and for the first time, from 1916 until 1919, Cadillac offered three commercial use platforms, described as Police Patrol (US$2,955), Ambulance (US$3,455) and Hearse (US$3,880) ($91,162 in 2019 dollars ). Although this car did not gain great popularity, it created the modern layout of an automobile that is still used today shared with other GM products. This layout became popular with the Austin 7, which copied the control layout from the Cadillac Type 53. The 1917 Type 55 was introduced with appearance changes, and cast aluminum is used when constructing the 2-door, 4-passenger Coupe. The choice of available body styles increases to 12, including the commercial versions. The Berline coach choice is renamed Imperial due to WWI as Cadillac didn't want to associate its products with Imperial Germany. For model year 1918, Cadillac offered a new coachwork option called the Type 57 Suburban which could accommodate seven passengers with a 132 in (3,353 mm) wheelbase, and was the first time GM used that description for one of their products with a retail price of US$4,090 ($69,521 in 2019 dollars ).
