Twitter is changing ownership, following a purchase by Elon Musk, who has explicitly said he intends to reorient the company's approach to online speech. Netflix, whose business model has long been predicated on sky's-the-limit growth, is bleeding subscribers. CNN+, a massively expensive project from what was once a dominant force in TV news, is shutting down a month after its launch. Facebook is losing regular users and taking a huge financial hit because of changes in the mobile ad space. Google is no longer the world's most popular website.
If there is a single lesson to be learned here, it is that the marketplace for online communications, entertainment, and news media is never stable, and even the most powerful players can be dethroned.
