I am aware that the embedded clips that I put of The Daily Show and The Colbert Report are not viewable in some other countries.
Another site suggests ways of viewing them in the UK.
This website (suggested by commenter freetheworld) seems to show an easy way of watching those two shows as well as Real Time with Bill Maher, though I am not sure if it works only for the UK.
Reader F in a comment to an earlier post has one suggestion for getting around national boundary restrictions:
Using a proxy address can help. One geo-associated with the U.S., in this case. You can even get browser extensions or small programs that make this really easy if you have occasion to proxy much.
I use proxies occasionally to watch AU, NZ, or UK items. Oddly, I don’t think I’ve ever needed one for content from any other country.
If there are readers of this blog in other countries who have yet other ways of seeing these clips, please let me know in the comments so that I can at least compile a list to help other readers.
Update 1: Josh Andrews in the comments adds:
All you have to do is modify the X-forwarded-For header field to a US ip address. I use the modify headers extension for firefox to do this.

Update 2: Jeremy in the comments adds:
If you search “hotspot shield” and use the free version, you will have access to a US-based VPN that allows you to access anything as if you were in the US. I use it to watch The Daily Show and Colbert, as well as Pandora, Netflix, etc.
