Usually I'm the first to really groan about media over-exposure, but sports fans have definitely benefited from the expanded coverage available the last few years. Now out-of-town fans can watch their team, albeit for a premium, and people of looser morals and greater computer technical abilities have a good crack at watching most anything they want on the plethora of international streams on the Internet.
And this has only helped out the Olympics this summer. Between coverage on all of their affiliates (CNBC, MSNBC, NBC, Universal on HD, etc.), Americans have a great deal of Olympic coverage available on TV. However, the real ace in the hole is the online coverage that streams almost every sporting event that they can through their main online hub, nbcolympics.com.
Most of the fun of the Olympics is seeing sports that you don't generally see - not even on ESPN 2 at 3 in the morning. Not even sports that gain marquee attention most every Olympics - swimming, track and field, and gymnastics standing out - but stuff like women's weight lifting, or fencing, or handball. Or badminton! I watched some of that with my dad yesterday morning and it was awesome in HD.
