Off the top of my head Enron in 2001, WorldCom in 2002, Lehman Brothers and AIG in 2008, and GM and Chrysler in 2009 all seem to be better fit than Blackberry for the 'century's biggest corporate disasters'.
I interpreted it as "one of the biggest corporate disasters of the last 14 years," and would give the author the benefit of the doubt that that is what she meant.
Seriously. I think the global oil companies will have something to show us about corporate disaster before the century is up.
In any case, 86 years is a lot of years remaining for someone to do a worse job than BlackBerry.
