Question: How many iPods did the creator of Safari reveal it sold in April of 2007?

full_context: Document 1: IPod: On October 21, 2008, Apple reported that only 14.21% of total revenue for fiscal quarter 4 of year 2008 came from iPods. At the September 9, 2009 keynote presentation at the Apple Event, Phil Schiller announced total cumulative sales of iPods exceeded 220 million. The continual decline of iPod sales since 2009 has not been a surprising trend for the Apple corporation, as Apple CFO Peter Oppenheimer explained in June 2009: "We expect our traditional MP3 players to decline over time as we cannibalize ourselves with the iPod Touch and the iPhone." Since 2009, the company's iPod sales have continually decreased every financial quarter and in 2013 a new model was not introduced onto the market.
Document 2: Macintosh: By March 2011, the market share of OS X in North America had increased to slightly over 14%. Whether the size of the Mac's market share and installed base is relevant, and to whom, is a hotly debated issue. Industry pundits have often called attention to the Mac's relatively small market share to predict Apple's impending doom, particularly in the early and mid-1990s when the company's future seemed bleakest. Others argue that market share is the wrong way to judge the Mac's success. Apple has positioned the Mac as a higher-end personal computer, and so it may be misleading to compare it to a budget PC. Because the overall market for personal computers has grown rapidly, the Mac's increasing sales numbers are effectively swamped by the industry's expanding sales volume as a whole. Apple's small market share, then, gives the impression that fewer people are using Macs than did ten years ago, when exactly the opposite is true. Soaring sales of the iPhone and iPad mean that the portion of Apple's profits represented by the Macintosh has declined in 2010, dropping to 24% from 46% two years earlier. Others try to de-emphasize market share, citing that it is rarely brought up in other industries. Regardless of the Mac's market share, Apple has remained profitable since Steve Jobs' return and the company's subsequent reorganization. Notably, a report published in the first quarter of 2008 found that Apple had a 14% market share in the personal computer market in the US, including 66% of all computers over $1,000. Market research indicates that Apple draws its customer base from a higher-income demographic than the mainstream personal computer market.

Document 4: Web browser: Apple's Safari had its first beta release in January 2003; as of April 2011, it had a dominant share of Apple-based web browsing, accounting for just over 7% of the entire browser market.
Document 5: Macintosh: In recent years, Apple has seen a significant boost in sales of Macs. This has been attributed, in part, to the success of the iPod and the iPhone, a halo effect whereby satisfied iPod or iPhone owners purchase more Apple products, and Apple has since capitalized on that with the iCloud cloud service that allows users to seamlessly sync data between these devices and Macs. Nonetheless, like other personal computer manufacturers, the Macintosh lines have been hurt by consumer trend towards smartphones and tablet computers (particularly Apple's own iPhone and iPad, respectively) as the computing devices of choice among consumers.
Document 6: 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 7: IPod: On April 9, 2007, it was announced that Apple had sold its one-hundred millionth iPod, making it the biggest selling digital music player of all time. In April 2007, Apple reported second quarter revenue of US$5.2 billion, of which 32% was made from iPod sales. Apple and several industry analysts suggest that iPod users are likely to purchase other Apple products such as Mac computers.
Document 8: IPod: Before the release of iOS 5, the iPod branding was used for the media player included with the iPhone and iPad, a combination of the Music and Videos apps on the iPod Touch. As of iOS 5, separate apps named "Music" and "Videos" are standardized across all iOS-powered products. While the iPhone and iPad have essentially the same media player capabilities as the iPod line, they are generally treated as separate products. During the middle of 2010, iPhone sales overtook those of the iPod.
Document 9: IPod: Since October 2004, the iPod line has dominated digital music player sales in the United States, with over 90% of the market for hard drive-based players and over 70% of the market for all types of players. During the year from January 2004 to January 2005, the high rate of sales caused its U.S. market share to increase from 31% to 65% and in July 2005, this market share was measured at 74%. In January 2007 the iPod market share reached 72.7% according to Bloomberg Online.
Document 10: Apple Inc.: At the Macworld Conference & Expo in January 2007, Steve Jobs introduced the long-anticipated iPhone, a convergence of an Internet-enabled smartphone and iPod. The first-generation iPhone was released on June 29, 2007, for $499 (4 GB) and $599 (8 GB) with an AT&T contract. On February 5, 2008, it was updated to have 16 GB of memory, in addition to the 8 GB and 4 GB models. It combined a 2.5G quad band GSM and EDGE cellular phone with features found in handheld devices, running a scaled-down version of OS X (dubbed iPhone OS after the launch and later renamed to iOS), with various Mac OS X applications such as Safari and Mail. It also includes web-based and Dashboard apps such as Google Maps and Weather. The iPhone features a 3.5-inch (89 mm) touchscreen display, Bluetooth, and Wi-Fi (both "b" and "g").A second version, the iPhone 3G, was released on July 11, 2008, with a reduced price of $199 for the 8 GB model and $299 for the 16 GB model. This version added support for 3G networking and assisted GPS navigation. The flat silver back and large antenna square of the original model were eliminated in favor of a glossy, curved black or white back. Software capabilities were improved with the release of the App Store, which provided iPhone-compatible applications to download. On April 24, 2009, the App Store surpassed one billion downloads. On June 8, 2009, Apple announced the iPhone 3GS. It provided an incremental update to the device, including faster internal components, support for faster 3G speeds, video recording capability, and voice control.
Document 11: Macintosh: Statistics from late 2003 indicate that Apple had 2.06 percent of the desktop share in the United States that had increased to 2.88 percent by Q4 2004. As of October 2006, research firms IDC and Gartner reported that Apple's market share in the U.S. had increased to about 6 percent. Figures from December 2006, showing a market share around 6 percent (IDC) and 6.1 percent (Gartner) are based on a more than 30 percent increase in unit sale from 2005 to 2006. The installed base of Mac computers is hard to determine, with numbers ranging from 5% (estimated in 2009) to 16% (estimated in 2005).
Document 12: IPod: On January 22, 2008, Apple reported the best quarter revenue and earnings in Apple's history so far. Apple posted record revenue of US$9.6 billion and record net quarterly profit of US$1.58 billion. 42% of Apple's revenue for the First fiscal quarter of 2008 came from iPod sales, followed by 21% from notebook sales and 16% from desktop sales.
Document 13: 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 14: Macintosh: From 2001 to 2008, Mac sales increased continuously on an annual basis. Apple reported worldwide sales of 3.36 million Macs during the 2009 holiday season. As of Mid-2011, the Macintosh continues to enjoy rapid market share increase in the US, growing from 7.3% of all computer shipments in 2010 to 9.3% in 2011. According to IDC's quarterly PC tracker, globally, in 3rd quarter of 2014, Apple's PC market share increased 5.7 percent year over year, with record sales of 5.5 million units. Apple now sits in the number five spot, with a global market share of about 6% during 2014, behind Lenovo, HP, Dell and Acer.
Document 15: IPod: On October 22, 2007, Apple reported quarterly revenue of US$6.22 billion, of which 30.69% came from Apple notebook sales, 19.22% from desktop sales and 26% from iPod sales. Apple's 2007 year revenue increased to US$24.01 billion with US$3.5 billion in profits. Apple ended the fiscal year 2007 with US$15.4 billion in cash and no debt.
