Question: On what day did the publisher of Internet Channel unveil the new systems?

full_context: Document 1: Web browser: Internet Explorer, on the other hand, was bundled free with the Windows operating system (and was also downloadable free), and therefore it was funded partly by the sales of Windows to computer manufacturers and direct to users. Internet Explorer also used to be available for the Mac. It is likely that releasing IE for the Mac was part of Microsoft's overall strategy to fight threats to its quasi-monopoly platform dominance - threats such as web standards and Java - by making some web developers, or at least their managers, assume that there was "no need" to develop for anything other than Internet Explorer. In this respect, IE may have contributed to Windows and Microsoft applications sales in another way, through "lock-in" to Microsoft's browser.
Document 2: Nintendo Entertainment System: As the 1990s dawned, gamers predicted that competition from technologically superior systems such as the 16-bit Sega Mega Drive/Genesis would mean the immediate end of the NES’s dominance. Instead, during the first year of Nintendo's successor console the Super Famicom (named Super Nintendo Entertainment System outside Japan), the Famicom remained the second highest-selling video game console in Japan, outselling the newer and more powerful NEC PC Engine and Sega Mega Drive by a wide margin. The console remained popular in Japan and North America until late 1993, when the demand for new NES software abruptly plummeted. The final Famicom game released in Japan is Takahashi Meijin no Bōken Jima IV (Adventure Island IV), while in North America, Wario's Woods is the final licensed game. In the wake of ever decreasing sales and the lack of new software titles, Nintendo of America officially discontinued the NES by 1995. However, Nintendo kept producing new Famicom units in Japan until September 25, 2003, and continued to repair Famicom consoles until October 31, 2007, attributing the discontinuation of support to insufficient supplies of parts.

Document 4: Nintendo Entertainment System: In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version". When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version"; therefore, the only differences between the two are the text on the front flap and texture on the top/bottom of the casing.
Document 5: Super Nintendo Entertainment System: Emulation of the SNES is now available on handheld units, such as Android devices, Apple's iPhone and iPad, Sony's PlayStation Portable (PSP), the Nintendo DS and Game Boy Advance, the Gizmondo, the Dingoo and the GP2X by GamePark Holdings, as well as PDAs. While individual games have been included with emulators on some GameCube discs, Nintendo's Virtual Console service for the Wii marks the introduction of officially sanctioned general SNES emulation, though SNES9x GX, a port of SNES9x, has been made for the Wii.
Document 6: Internet Channel: The Internet Channel is a version of the Opera 9 web browser for use on the Wii by Opera Software and Nintendo. Opera Software also implemented the Nintendo DS Browser for Nintendo's handheld system.
Document 7: Nintendo Entertainment System: At June 1985's Consumer Electronics Show (CES), Nintendo unveiled the American version of its Famicom. This is the system which would eventually be officially deployed as the Nintendo Entertainment System, or the colloquial "NES". Nintendo seeded these first systems to limited American test markets starting in New York City on October 18, 1985, following up with a full-fledged North American release of the console in February of the following year. Nintendo released 17 launch titles: 10-Yard Fight, Baseball, Clu Clu Land, Duck Hunt, Excitebike, Golf, Gyromite, Hogan’s Alley, Ice Climber, Kung Fu, Pinball, Soccer, Stack-Up, Tennis, Wild Gunman, Wrecking Crew, and Super Mario Bros.h[›] Some varieties of these launch games contained Famicom chips with an adapter inside the cartridge so they would play on North American consoles, which is why the title screen of Gyromite has the Famicom title "Robot Gyro" and the title screen of Stack-Up has the Famicom title "Robot Block".
Document 8: Web browser: In January 2009, the European Commission announced it would investigate the bundling of Internet Explorer with Windows operating systems from Microsoft, saying "Microsoft's tying of Internet Explorer to the Windows operating system harms competition between web browsers, undermines product innovation and ultimately reduces consumer choice." Microsoft Corp v Commission
Document 9: Nintendo Entertainment System: Video output connections varied from one model of the console to the next. The original HVC-001 model of the Family Computer featured only radio frequency (RF) modulator output. When the console was released in North America and Europe, support for composite video through RCA connectors was added in addition to the RF modulator. The HVC-101 model of the Famicom dropped the RF modulator entirely and adopted composite video output via a proprietary 12-pin "multi-out" connector first introduced for the Super Famicom/Super Nintendo Entertainment System. Conversely, the North American re-released NES-101 model most closely resembled the original HVC-001 model Famicom, in that it featured RF modulator output only. Finally, the PlayChoice-10 utilized an inverted RGB video output.
Document 10: List of Super Nintendo Entertainment System games: Of the console's 783 official releases, 249 were exclusive to North America and 62 to Europe. The Super NES was released in North America on August 23, 1991 with its launch titles being Super Mario World, F - Zero, Pilotwings, SimCity, and Gradius III. The last game to be officially published for the system was Frogger in 1998. The best - selling game is Super Mario World with over 20.6 million units sold. Despite the console's relatively late start, and the fierce competition it faced in North America and Europe from Sega's Genesis / Mega Drive console, it was the best - selling console of its era.
Document 11: Nintendo Entertainment System: The Nintendo Entertainment System (commonly abbreviated as NES) is an 8 - bit home video game console that was developed and manufactured by Nintendo. 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) (also known by the portmanteau abbreviation Famicom (ファミコン, Famikon) and abbreviated as FC) on July 15, 1983, and was later released in North America during 1985, in Europe during 1986 and 1987, and Australia in 1987. In South Korea, it was known as the Hyundai Comboy (현대컴보이 Hyeondae Keomboi) and was distributed by SK Hynix which then was known as Hyundai Electronics. The best - selling gaming console of its time, the NES helped revitalize the US video game industry following the video game crash of 1983. With the NES, Nintendo introduced a now - standard business model of licensing third - party developers, authorizing them to produce and distribute titles for Nintendo's platform. It was succeeded by the Super Nintendo Entertainment System.
Document 12: Nintendo Entertainment System: For its complete North American release, the Nintendo Entertainment System was progressively released over the ensuing years in four different bundles: the Deluxe Set, the Control Deck, the Action Set and the Power Set. The Deluxe Set, retailing at US$199.99 (equivalent to $475 in 2016), included R.O.B., a light gun called the NES Zapper, two controllers, and two Game Paks: Gyromite, and Duck Hunt. The Basic Set, retailing at US$89.99 with no game, and US$99.99 bundled with "Super Mario Bros." The Action Set, retailing in 1988 for US$149.99, came with the Control Deck, two game controllers, an NES Zapper, and a dual Game Pak containing both Super Mario Bros. and Duck Hunt. In 1989, the Power Set included the console, two game controllers, a NES Zapper, a Power Pad, and a triple Game Pak containing Super Mario Bros, Duck Hunt, and World Class Track Meet. In 1990, a Sports Set bundle was released, including the console, an NES Satellite infrared wireless multitap adapter, four game controllers, and a dual Game Pak containing Super Spike V'Ball and Nintendo World Cup. Two more bundle packages were later released using the original model NES console. The Challenge Set of 1992 included the console, two controllers, and a Super Mario Bros. 3 Game Pak for a retail price of US$89.99. The Basic Set, first released in 1987, was repackaged for a retail US$89.99. It included only the console and two controllers, and no longer was bundled with a cartridge. Instead, it contained a book called the Official Nintendo Player's Guide, which contained detailed information for every NES game made up to that point.
Document 13: Web browser: Microsoft responded with its Internet Explorer in 1995, also heavily influenced by Mosaic, initiating the industry's first browser war. Bundled with Windows, Internet Explorer gained dominance in the web browser market; Internet Explorer usage share peaked at over 95% by 2002.
Document 14: Internet Explorer Mobile: Internet Explorer Mobile (formerly named Pocket Internet Explorer; later called IE Mobile) is a discontinued mobile browser developed by Microsoft, based on versions of the Trident layout engine. IE Mobile comes loaded by default with Windows Phone and Windows CE. Later versions of Internet Explorer Mobile (since Windows Phone 8) are based on the desktop version of Internet Explorer. Older versions however, called Pocket Internet Explorer (found on Windows Phone 7 and Windows Mobile), are not based on the same layout engine.
Document 15: The Legend of Zelda: Twilight Princess: Aonuma had anticipated creating a Zelda game for what would later be called the Wii, but had assumed that he would need to complete Twilight Princess first. His team began work developing a pointing-based interface for the bow and arrow, and Aonuma found that aiming directly at the screen gave the game a new feel, just like the DS control scheme for Phantom Hourglass. Aonuma felt confident this was the only way to proceed, but worried about consumers who had been anticipating a GameCube release. Developing two versions would mean delaying the previously announced 2005 release, still disappointing the consumer. Satoru Iwata felt that having both versions would satisfy users in the end, even though they would have to wait for the finished product. Aonuma then started working on both versions in parallel.[o]
