Question: What was Nintendo's limit on games per developer per year for the platform supporting the video game named after the sports organisation in charge of the Super Bowl halftime show?

<P0-S0> NFL is a 1989 football video game, developed by Atlus and published by LJN exclusively for the Nintendo Entertainment System. <SEP> <P1-S0> It was initially released in Japan as the Family Computer (Japanese: ファミリーコンピュータ, Hepburn: Famirī Konpyūta?) <P1-S1> (also known by the portmanteau abbreviation Famicom (ファミコン, Famikon?) <P1-S2> and abbreviated as FC) on July 15, 1983, and was later released in North America during 1985, in Europe during 1986, and Australia in 1987. <P1-S3> In South Korea, it was known as the Hyundai Comboy (현대 컴보이 Hyeondae Keomboi) and was distributed by SK Hynix which then was known as Hyundai Electronics. <P1-S4> It was succeeded by the Super Nintendo Entertainment System. <P1-S5> The Nintendo Entertainment System (also abbreviated as NES) is an 8-bit home video game console that was developed and manufactured by Nintendo. <SEP> <P2-S0> nintendo was not as restrictive as sega, which did not permit third-party publishing until mediagenic in late summer 1988. nintendo's intention, however, was to reserve a large part of nes game revenue for itself. <P2-S1> nintendo required that they be the sole manufacturer of all cartridges, and that the publisher had to pay in full before the cartridges for that game be produced. <P2-S2> cartridges could not be returned to nintendo, so publishers assumed all the risk. <P2-S3> as a result, some publishers lost more money due to distress sales of remaining inventory at the end of the nes era than they ever earned in profits from sales of the games. <P2-S4> because nintendo controlled the production of all cartridges, it was able to enforce strict rules on its third-party developers, which were required to sign a contract by nintendo that would obligate these parties to develop exclusively for the system, order at least 10,000 cartridges, and only make five games per year. <P2-S5> a 1988 shortage of dram and rom chips also reportedly caused nintendo to only permit 25% of publishers' requests for cartridges. <P2-S6> this was an average figure, with some publishers receiving much higher amounts and others almost none. <P2-S7> gamespy noted that nintendo's "iron-clad terms" made the company many enemies during the 1980s. <P2-S8> some developers tried to circumvent the five game limit by creating additional company brands like konami's ultra games label; others tried circumventing the 10nes chip. <SEP> <P3-S0> However, competition from Sega's console brought an end to this practice; in 1991, Acclaim began releasing games for both platforms, with most of Nintendo's other licensees following suit over the next several years; Capcom (which licensed some games to Sega instead of producing them directly) and Square were the most notable holdouts. <P3-S1> During the NES era, Nintendo maintained exclusive control over titles released for the system—the company had to approve every game, each third-party developer could only release up to five games per year (but some third parties got around this by using different names, for example Konami's "Ultra Games" brand), those games could not be released on another console within two years, and Nintendo was the exclusive manufacturer and supplier of NES cartridges. <SEP> <P4-S0> the super bowl xlvii halftime show occurred on february 3, 2013 at the mercedes - benz superdome in new orleans as part of super bowl xlvii and featured american entertainer beyoncé with special guests kelly rowland and michelle williams from destiny's child. <P4-S1> the show was produced by ricky kirshner and directed by hamish hamilton. <P4-S2> it received acclaim from music critics who commented that beyoncé once more proved her abilities during live performances. <P4-S3> it became the then second most watched show in super bowl history by garnering 110.8 million viewers. <P4-S4> the performance, and the stadium blackout that followed, generated more than 299,000 tweets per minute, making it the then second most tweeted moment in the history of twitter. <P4-S5> this would be the first pepsi sponsored halftime show since prince's performance in super bowl xli. <SEP> <P5-S0> Super Bowl XXVII halftime show with Michael Jackson provided an exception, as the NFL and Frito - Lay agreed to make a donation and provide commercial time for Jackson's Heal the World Foundation. <P5-S1> According to Nielsen SoundScan data, the halftime performers regularly experience significant spikes in weekly album sales and paid digital downloads due to the exposure. <P5-S2> For Super Bowl XLIX, it was reported by the Wall Street Journal that league officials asked representatives of potential acts if they would be willing to provide financial compensation to the NFL in exchange for their appearance, in the form of either an up - front fee, or a cut of revenue from concert performances made after the Super Bowl. <P5-S3> The NFL does not pay the halftime show performers an appearance fee, though it covers all expenses for the performers and their entourage of band members management, technical crew, security personnel, family, and friends. <P5-S4> While these reports were denied by an NFL spokeswoman, the request had, according to the Journal, received a ``chilly ''response from those involved.
