5 years. And yet it seems it had been there forever, right? Well apparently 5 years ago if you wanted to watch an online video you had to download a crappy MPG file or wait for those quicktimes to stream. And then along came two guys and their garage, and they changed the web forever. Without them we wouldn’t have the amazed lemur, the skateboarding dog, the laughing baby and many other classics of web 2.0 entertainment. Happy birthday Youtube! Too see (among other things) the Youtube timeline click on the number 5 next to their logo.
