Well unfortunately yes those are some of the most valuable industries in the world - it's way beyond yearbooks - it is the potential of replacing ALL communication to people you know. It's not just blockbuster's killer but potentially a company that will own/control the distribution of all entertainment. and the last one isn't just taxis but the potential to be (with sound competition) a possible future replacement of car ownership altogether. I'm not saying they have a great chance of making it that far, but yes, that's why people invest in them.
