Background: Cuban was born in Pittsburgh, Pennsylvania. His father, Norton Cuban, was an automobile upholsterer, while Cuban has described his mother, Shirley, as someone with "a different job or different career goal every other week." He grew up in the suburb of Mount Lebanon, in a Jewish working-class family. His paternal grandfather changed the family name from "Chabenisky" to "Cuban" after his family emigrated from Russia through Ellis Island.
Context: On November 17, 2008, it was reported that the U.S. Securities and Exchange Commission (SEC) filed a civil suit against Cuban relating to alleged insider trading in the shares of Mamma.com, now known as Copernic. A stock dilution occurred shortly after a trade in June 2004, giving hints of inside knowledge at the time of the trade, and Cuban allegedly was saved from a loss of $750,000. The SEC claimed that Cuban ordered the sale of his holdings in Mamma.com after he had been confidentially approached by the company to participate in a transaction likely to dilute shares of current shareholders. Cuban disputed the charges, saying he had not agreed to keep the information secret. On his blog, Cuban contended the facts were false and that the investigation was "a product of gross abuse of prosecutorial discretion". DealBook, a section of The New York Times, reported through an anonymous source that Cuban believed the investigation was motivated by an SEC employee having taken offense to his interest in possibly distributing the film Loose Change. In July 2009, the U.S. District Court dismissed the charges against Cuban, and the SEC appealed. In September 2010, an appeals court said that the district court had erred and that further proceedings would be necessary to address the merits of the suit. A federal jury in Texas found in favor of Cuban on October 16, 2013. The nine-member jury issued the verdict after deliberating 3 hours and 35 minutes. In March 2014, Cuban was on air at CNBC criticizing high-frequency trading (HFT). Those against HFT, such as Cuban, believe the technology is equivalent to automated insider trading.

Background: For the upcoming film about the superhero character, see Aquaman (film). Aquaman is a fictional superhero appearing in American comic books published by DC Comics. Created by Paul Norris and Mort Weisinger, the character debuted in More Fun Comics #73 (November 1941). Initially a backup feature in DC's anthology titles, Aquaman later starred in several volumes of a solo comic book series.
Context: Aquaman's first origin story was presented in flashback from his debut in More Fun Comics #73 (November 1941), narrated by the character himself: The story must start with my father, a famous undersea explorer--if I spoke his name, you would recognize it. My mother died when I was a baby, and he turned to his work of solving the ocean's secrets. His greatest discovery was an ancient city, in the depths where no other diver had ever penetrated. My father believed it was the lost kingdom of Atlantis. He made himself a water-tight home in one of the palaces and lived there, studying the records and devices of the race's marvelous wisdom. From the books and records, he learned ways of teaching me to live under the ocean, drawing oxygen from the water and using all the power of the sea to make me wonderfully strong and swift. By training and a hundred scientific secrets, I became what you see--a human being who lives and thrives under the water. In his early Golden Age appearances, Aquaman can breathe underwater and control fish and other underwater life for up to a minute. Initially, he was depicted as speaking to sea creatures "in their own language" rather than telepathically, and only when they were close enough to hear him (within a 20 yards (18 m) radius). Aquaman's adventures took place all across the world, and his base was "a wrecked fishing boat kept underwater," in which he lived. During his wartime adventures, most of Aquaman's foes were Nazi U-boat commanders and various Axis villains where he once worked with the All-Star Squadron. The rest of his adventures in the 1940s and 1950s had him dealing with various sea-based criminals, including modern-day pirates such as his longtime archenemy Black Jack, as well as various threats to aquatic life, shipping lanes, and sailors. Aquaman's last appearance in More Fun Comics was in issue #107, before being moved along with Superboy and Green Arrow to Adventure Comics, starting with issue #103 in 1946.
