Problem: Isabella I (Spanish: Isabel, 22 April 1451 - 26 November 1504) reigned as Queen of Castile from 1474 until her death. Her marriage to Ferdinand II of Aragon became the basis for the political unification of Spain under their grandson, Charles I. After a struggle to claim her right to the throne, she reorganized the governmental system, brought the crime rate to the lowest it had been in years, and unburdened the kingdom of the enormous debt her brother had left behind.

At the end of the Reconquista, only Granada was left for Isabella and Ferdinand to conquer. The Emirate of Granada had been held by the Muslim Nasrid dynasty since the mid-13th century. Protected by natural barriers and fortified towns, it had withstood the long process of the reconquista. On 1 February 1482, the king and queen reached Medina del Campo and this is generally considered the beginning of the war for Granada. While Isabella's and Ferdinand's involvement in the war was apparent from the start, Granada's leadership was divided and never able to present a united front. It still took ten years to conquer Granada, however, culminating in 1492.  The Spanish monarchs recruited soldiers from many European countries and improved their artillery with the latest and best cannons. Systematically, they proceeded to take the kingdom piece by piece. In 1485 they laid siege to Ronda, which surrendered after only a fortnight due to extensive bombardment. The following year, Loja was taken, and again Muhammad XII was captured and released. One year later, with the fall of Malaga, the western part of the Muslim Nasrid kingdom had fallen into Spanish hands. The eastern province succumbed after the fall of Baza in 1489. The siege of Granada began in the spring of 1491 and at the end of the year, Muhammad XII surrendered. On 2 January 1492 Isabella and Ferdinand entered Granada to receive the keys of the city, and the principal mosque was reconsecrated as a church. The Treaty of Granada was signed later that year, and in it Ferdinand and Isabella gave their word to allow the Muslims and Jews of Granada to live in peace. An uprising by the Moors in 1500 caused the Catholic side to consider that the Moors had violated the Treaty: this gave them a justification for revoking its provisions. See Morisco Revolt.  During the war, Isabella noted the abilities and energy of Gonzalo Fernandez de Cordoba and made him one of the two commissioners for the negotiations. Under her patronage, De Cordoba went on to an extraordinary military career that revolutionised the organisation and tactics of the emerging Spanish military, changing the nature of warfare and altering the European balance of power.

Problem: The Jay Leno Show is an American talk show created by and starring Jay Leno. Premiering on NBC on September 14, 2009, the program aired on weeknights at 10:00 p.m. ET/PT through February 9, 2010. The program was modeled upon the format of a late night talk show--specifically, Jay Leno's incarnation of The Tonight Show, opening with a comedic monologue, followed by interviews with celebrity guests and other comedy segments. Sketches from The Tonight Show (including Headlines and Jaywalking) were carried over to The Jay Leno Show, along with new sketches.

Leno had a contract for five years  for the show. NBC reportedly had an option to cancel after two years, but had committed to at least one or two years regardless of ratings, although later chose to end the show after less than five months. He could have earned up to $30 million each year depending on ratings for Leno, compared to a $20 million annual salary during his last years at Tonight.  NBC expected to benefit by offering an inexpensive comedic alternative to the procedurals ("100% more comedy and 98% fewer murders!") and other one-hour dramas that typically air at 10 pm, and by offering new episodes 46 weeks each year versus 22. While Leno was not necessarily expected to be competitive with the higher-rated scripted shows on ABC and CBS in its time slot, its projected cost of production was far lower and thus it was expected to be profitable to the network, and product integration intended to make the show "as DVR-proof as you can be on television in this era". Each airing of Leno cost about $350,000 to $400,000 versus up to $3 million for an hour-long drama, saving NBC $13 million each week without the network needing the show to beat its competitors. Those costs include the services of 22 writers, whom Leno called the "top 5% of the highest-paid . . . in the Guild."  McDonald's became the first buying advertiser for the program, tying in their "Million Dollar Roll" nightly in October 2009 promoting that year's version of McDonald's Monopoly.

What other financial impact did the show have?

Problem: 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.

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.
