If you're feeling nostalgic for the shows of your childhood, Nick Reboot streams shows such as Rocko's Modern Life, Are You Afraid of the Dark and Hey Arnold! 24 hours a day, for free. All you need to do is head to the website and start streaming.
It will determine where you are and optimise the streaming quality depending on whether you're closer to the East or West ingest server. You can even chat with other streamers while you watch and reminisce about the good ol' days.
If you're wondering if this is all legal, it is apparently. Nick Reboot is a non-commercial and non-profit website, dedicated to providing a medium for commentary, criticism, educational review and research of the TV network Nickelodeon during the '90s and early 2000s. By operating under the doctrine of "fair use" codified in section 107 of US copyright law, the site is able to stream classic Nickelodeon shows.
The catch is that you don't have any control of you want to watch. Everything is cued up and streamed as if it were a real TV network -- toy commercials included! To travel back in time and watch the ongoing stream, check the link below.
