I keep discovering new networks that are part of the Olympic coverage. The first four or five days I was only aware of NBC, MSNBC and CNBC. Day before yesterday I discovered the Oxygen channel. Today I discovered USA Network. Am I missing any networks?
Any networks owned by NBC will probably have coverage. Those you listed are all NBC-owned, though I am not 100% sure about Oxygen, it almost has to be.
We had the worst coverage of the olympics in Australia. Ours was done by channel 7 and it was horrible they never showed a full game of basketball and just kept cutting in between every game never showing a full event. The network owns 6 different hd channels and they all had the same coverage, was so disappionted with the olympics mainly cause of the coverage.
