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.

Question: The creator of Safari has remained profitable since what time?
Answer: Steve Jobs' return

Rhapsody was the code name given to Apple Computer's next-generation operating system during the period of its development between Apple's purchase of NeXT in late 1996 and the announcement of Mac OS X (now called "macOS") in 1998. At first more than an operating system, Rhapsody represented a new strategy for Apple, who intended the operating system to run on x86-based PCs and DEC Alpha workstations as well as on PowerPC-based Macintosh hardware. In addition, the underlying API frameworks would be ported to run natively on Microsoft Windows NT. Eventually, the non-Apple platforms were dropped, and later versions consisted primarily of the OPENSTEP operating system ported to the Power Macintosh, along with a new GUI to make it appear more Mac-like. Several existing "classic" Mac OS technologies were also ported to Rhapsody, including QuickTime and AppleSearch. Rhapsody could also run Mac OS 8 in a "Blue Box" emulation layer.

Question: When did the iPhone 6 by the developer of Rhapsody come out?
