Who would have thought a few years ago that Yahoo would end up in such a mess? It is just like imagining that Google ends up teaming with Microsoft too in a few years. Yahoo had brand, the main search engine, a great leadership team, great technology, Silicon Valley credibility...the lot.
Another old timer in a bad way is AOL. Once worthy of a $100 billion merger, now worth maybe 5% of that. The world of tech moves fast, it is one reason I stay away from tech share prices. Too much disruptive technology to make anything a sure bet.
