On second thoughts, don't. YouTube's such an ingrained part of the Internet that it's all too easy to forget that it's actually only seven years old. That's seven years of highlights such as RickRolling, Rebecca Black's Friday and too many cat videos to count. Wait a minute. Why am I celebrating that? I would try to pick the video that was uploaded just as YouTube turned seven, but what with it hitting more than an hour's worth of content every single second, that would be somewhat tricky to manage. What can be embedded is YouTube's first video, which is below. It's almost quaint.
