BlackBerry was awesome in its day. A real lesson, as with Nokia, and AOL/Time Warner, as how world domination is not something carved in stone in the wilderness of the free markets.
Each, however also changed because of platform shifts. AOL fell when broadband replaced dial up. BlackBerry when email was pushed down the priority ladder to internet and smart phone. No,is when voice became less a priority than internet and smart phone.
So many vendors continue to lose out when others come in with the new cloud platform. Will 5G do the same, etc.
Good to understand how this works in terms of CAP analysis. It usually takes a new disruptive platform to unseat the old dominator. Roku provides the opening for many more channels that can compete with Netflix as does the smart tv platform, where before only Netflix could always be there.

Good call, and a timely reminder of the real risk involved with paying very high premiums for SaaS companies: the assumption is that their rapid growth will bring down valuations into more normal regions over time - which they will, provided their leadership position isn’t upset by a disruptive new technology or trend before that calculation works out.
