Just because Amazon trademarked a name does not mean that they will actively be looking to use that name. Often companies trademark names to avoid others using the name. Some companies trademark the weirdest names and even trademark misspelled names similar to their products, just to protect themselves. Obviously that does not mean that there is no chance that they actually DO make a Youtube competitor, I just feel like it's very unlikely. For instance, why would they even want to? From what I understand Youtube is still not profitable to this day. What is in it for them, except for the same pain in the a** issues with advertisers and all that stuff that Youtube has been battling the last couple of years. Another great question: why would they launch a new platform and not just build on Twitch, which has been expanding to cooking, traveling, talkshows, crafts etc. in the last years? The example about Google+ is also a very valid one. People don't just randomly switch platforms. It takes a ton of money to get people to switch and even more to keep them on a platform. If you are going to bet your money on Amazon, you might as well just go to Twitch right now.
