History lesson:
The program was originally built for software company Macromedia in the late 1990's, but they decided not to release it as it didn't fit the direction they were heading (web based), and also had some clearance issues if they decided to proceed to market.
In 1999 it was acquired by Apple and released as Final Cut Pro (FCP).
In 2003 a cut down version of the program was released called Final Cut Express (FCE), which was the same program for a cheaper price, but with some built in limitations.
By 2006 Apple was selling FCP (then version 5.1) bundled with various other editing tools (Soundtrack, LiveType, Motion etc) as "Final Cut Studio".
In 2009 Apple released the final version of the "original" iteration of the software - FCP 7.
After only a decade, Apple had managed to forge roads into the film/tv industry, with many motion pictures and tv series being editing on Macs using the Final Cut Studio, likely paired with Apple's flagship PowerMac G5, and later Mac Pro - although it could happily run on a lowly G4 eMac if you had long enough for the rendering.
Two years later in 2011 Apple released "FCP X" (ie version 10) - a complete rebuild (and the first version that was 64-bit), with an entirely new interface and methodology to video editing. At launch, the industry largely dismissed the new program as not being a viable upgrade path from FCP7, and many of those who had made the switch to Final Cut abandoned Apple and went back to Avid or something else.
(The general consensus tends to be that FCPX was neither stable nor ready for market, which when combined with the major leap away from traditional time-line-based editing, made it easier for the professionals to turn to alternatives rather than stick with Apple.)
10 years later? I actually don't really know myself what's become of FCPX / FCP. I've just done some googling, and it appears Apple has recovered the initial lost ground when they made the big change from 7 to X. (As noted - the "X" has been dropped now - it's just called Final Cut Pro again) Apparently most serious film/tv editing is done on either Adobe Premiere, or Final Cut Pro, and FCP has a large chunk of that market share.
So - well done Apple if that's the case.
