It's not my intention to advertise but to help people who are unable to watch in on television. I did this with iStart a Fanwar and a good amount of people from the forum showed up. Anyway on my live tv website, you can watch Nickelodeon live here
Just go to the drop down menu and choose Nickelodeon and the channel will start, there's also a clock there so you can see when it's 8pm.
Oh and it's all free too! Hope you guys enjoy it!
Anyway, when the stream loads press the little X in the upper with hand corner of the ad centered in the middle of the stream video and Nickelodeon will play automatically. There's also a chat under the stream as well.
