BlackBerry global smartphone market share

American amusement-park ride injuries climbing as BlackBerry's smartphone market share collapses. Two completely unrelated industries on opposite trajectories: one managing the same daily safety budget while attendance grows, one losing the entire premise of its business in real time.

US amusement-park ride injuries climbed across this window as park attendance grew and reporting standards improved. BlackBerry's global smartphone market share collapsed from about 20 percent in 2007 to under 1 percent by 2016 as iPhone and Android replaced the QWERTY-keyboard-and-email default. Two completely unrelated lines on opposite trajectories sharing a window because the same nine years saw an entertainment-industry safety statistic grow with attendance and a smartphone incumbent collapse against a new paradigm.

One industry grew with its inputs. Another lost on the merits. The decade was uneven about what it preserved.
