The most famous new-media example of this trope is Hulu, which you've probably seen linked to in a forum. It constantly bills itself as offering free (albeit ad-supported), legal TV over the Internet, and they're right... as long as you live in the United States or Japan. If you're not, all you get is an error message. Note that this even applies to shows which air legally on regular TV outside America — you can't even watch an episode that aired last week which you might have missed.
This is particularly frustrating if the only reason you find yourself outside the United States is because you enlisted in its armed forces and are currently deployed overseas.
Hulu has also specifically blocked the PlayStation 3, which was briefly fully capable of playing video from the site in your living room. It now forces you to buy a paid premium service if you ever visit the site on a console, handheld or mobile device.
Additionally frustrating now that Hulu has begun hosting exclusive series such as the award-winning Pink, though the series eventually was made available (officially) through YouTube, after everyone had stopped caring.
Hulu is the worst offender in this regard in the anime market. Anime producers back in Japan always treat the United States and Canada as a single market when licencing out their titles, but when a North American distributor puts any anime titles it has licenced exclusively on Hulu, Canadian fans of said titles are left with essentially no legal way of streaming them online. The most infamous North American distributor that does this is Viz Media. It has had a contract with Hulu ever since 2008 to carry its subtitled anime releases in the United States, and has not had an equivalent agreement in place for Canada since the failure of Joost in 2009. And since April of 2014, all of Viz Media's English-dubbed releases are subject to this blackout in Canada as well. Viz had maintained for two years that it would have a way for Canadians to watch its streaming offerings "soon", but as all external indications said it would never happen, Viz subsequently withdrew that statement.
The BBC iPlayer does this to anyone and everyone outside the UK, even continental Europeans who have access to all the BBC channels. Which is because to watch TV in the UK, you must pay the license fee, which funds the BBC. In late July 2011 BBC iPlayer was made available to European users, albeit for a fee. In May 2015, however, this service was discontinued.
Other TV networks in the UK. i.e. ITV, Four and Five does this as well.
The UK service TVCatchUp does this as well.
The Belgian/Dutch public channel versions of the iPlayer are also not available to foreigners.
On top of this, the Moral Guardians made ARD (German public channel) block people from viewing 12+ content on their version of the iPlayer before their watershed. Making the whole service less than useful.
Update: since at least 2012 there has been an international version of iPlayer available which allows viewing of a selected number of shows for free (usually stuff like old episodes of Doctor Who and a fee-based service for other content. Not everything available on iPlayer in the UK is available on the international version, however, and the fee-based service is largely only open to European countries, the Americas and Asians still get the short end of the stick. And to make things worse, in 2014 there are rumors that the service may get discontinued due to budget cuts, which became true in May 2015 when the pay iPlayer service covering Europe was shut down, as mentioned above.
It eventually surfaced that the reason the Americas can't get an iPlayer is due to mutiny, many pay TV providers threatened to drop BBC America if they proceeded to launch the service in the US. 
The ABC Australia's iView service also performs this stupidity; the only difference is that Australians were never required to pay for a TV license. The reason given by the service is that it's not available overseas due to copyright reasons. Sure, that gives you the right to block imported content that airs on pay channels elsewhere (i.e. Madeline), but why are shows produced by the ABC themselves also blocked?
YouTube has bouts of idiocy where it suddenly blocks access to an official music video by an international artist in certain countries. To make matters worse, about 85% of music videos in YouTube were moved to a service named Vevo (which is run by YouTube in conjunction with the major record labels), which is basically Hulu for music videos (complete with the US-only availability).
YouTube is officially in the list for people outside the US and UK. Almost all official content on the site may be blocked from viewers whose IP address is known to be from outside the US or UK, depending on the content providers' whim and fancy. If they're feeling generous, you get content without sound. Otherwise, you won't be able to access the content at all, even if the content's a 8-bit remix of a copyrighted song, i.e. D-Pad Hero clips, which is stupid considering the fact that D-Pad Hero is homebrew and can be freely downloaded by anyone from just about anywhere in the world.
It goes from annoying to downright rage inducing when certain videos from US and UK-based record labels block videos in countries from where the artist is from.
However, quite a bit of video content from "geo-locked" websites often ends up on YouTube worldwide.
Some channels that can legally upload entire episodes, like MANGAentertainment, will have the rather grating habit of region-locking a few episodes, but not the rest of the same series. So, your experience will be something like: "Whoa, they took it to a whole new level! Wonder what's going to happen in the next episode... no, you've got to be kidding!" give or take a couple long groan of frustration.
Toei's YouTube Channel has this also for other countries, similar to MANGA's above.
It can get to a point where the YouTube video could be blocked in every country, courtesy of a DMCA takedown.
With the launch of its subscription service YouTube Red, a new policy began, requiring all Partner Program members to accept terms allowing ad-free playback and videos to be downloaded for offline play through its apps for subscribers. If a partner does not agree to this policy, its content is automatically geoblocked in all regions where the service is currently active (which, on the other hand, is few; only Australia, New Zealand, South Korea, and of course the United States), regardless of whether the user is a subscriber or not. This rule created notable havoc over Japanese and Korean content (particularly music), as Japan's music industry is much more protective over their content.
While most radio stations have no qualms about webstreaming worldwide (although some do replace the commercials), many Clear Channel stations block webstreaming outside of the US for licensing reasons.
And CBS Radio jumped on the "No Streaming For You" bandwagon in early 2010.
Disney's been doing it on and off with Radio Disney. When they launched in the late 90s, it was available as a RealPlayer stream worldwide. Then it went down for decentralization in late 1999. They started transmitting again in early 2000, but now because each state has their own RD affiliate, having online streaming now seems unlikely. Then Apple carried the New York Affiliate over Quick Time 4 as a showcase of their then-new Quick Time Streaming Media feature in early-2002. Then the stream stopped and Disney remerges back into a single network circa 2004, and it was at this time that the no export madness started- Apparently they started transmitting internationally again in 2005, but stopped soon after. By then the station had gone through Network Decay anyway and many international listeners who tuned in for the oldies and lullabies slots are no longer interested because those slots are long gone.
Up to 90% of the traffic generated by thepiratebay.org are American TV-shows that have been recorded the night before.
Of course, considering the popularity of American shows in many foreign markets, popular American shows are guaranteed to be exported.
Not always true: there's a lot of British/American shows that will never be aired again despite critical/commercial acclaim.
Some of Microsoft's services, such as Windows Marketplace and Games for Windows Live are only available in selected countries. Sure, the list is long, but it doesn't cover all of the world, much to the dismay of anyone living in the remaining countries.
For reasons incomprehensible to the human mind, Nickelodeon UK/US and Disney UK/US does this for video clips hosted on their sites as well.
Kewlopolis' Kewltoons video on demand site does this as well, despite the content on their site being either aired on TV elsewhere in the world or readily available on DVDs.
The BBC's official Doctor Who website often makes original content available - webisodes, games, etc - but blocks access to anyone outside the UK. The irony being most video-related content shows up on tube sites within minutes anyway.
This is particularly true of a series of free Adventure Games released since 2010. Although the games are later issued internationally for a fee via a third-party service, it qualifies as Bad Exportfor You due to the fact only the Windows version of the games is circulated, and not the Mac OS version available in the UK.
It should be noted that during the 2011 season of Doctor Who, international access improved somewhat on the Doctor Who site, with some videos now being made available for international viewing, specifically a series of online episode prequels. Others, like interviews and some trailers, remained geolocked. Videos related to the spin-off series The Sarah Jane Adventures remain UK-only. By 2013, however, it became rare for any of BBC's Doctor Who-related online content to be restricted to the UK, although the occasional item remains.
"Rai televisione" (Rai television), a TV station that was created to help expanding Italian culture, has a service called "Televisione diretta" (Direct television) which allows people to watch it online: ... but it's only available if you live in Italy.
The video-sharing site Veoh decided to block access to its site in multiple countries. According to them, this was due to the relatively low amount of traffic coming from said countries.
Australia gets screwed arguably the worst by this. It has games simply vanish from the service, and if they aren't, a lot of them charge two to three times as much as an American version of the game for the exact same thing. The worst example of this was Call of Duty, which was listed at the most expensive prices (which are all in Us Dollars).. the Australian dollar proceeded to tank, increasing the price to over $120 USD.
It's the publisher of the game that tells Valve whether or not to make a game available in a region, and also dictate the price of the game in the region. So if Bully isn't available in your Steam store, don't blame Valve, blame 2K Games. And if Dead Space 2 costs US$14.99 in your area instead of US$4.99 elsewhere during the Steam Summer Sales, blame EA, not Valve. That said, we in South East Asia share your pain—yeah, they're pricing it at US$14.99 in South East Asia too...
Australia and Germany get an inferior version of Team Fortress 2 and Left 4 Dead 2 compared to the rest of the world due to the Moral Guardians' meddling, and this is made possible thanks to Steam's ability to region-lock.note The uncensored version of L4D2 was finally released in Australia when its new rating was introduced specifically designed for M-rated games. The same can not be said for Germany, though (but hey, at least they get some Counter-Strike weapons no one else can normally get).
Many of Nickelodeon's tie-in websites start their life as being open to all countries, but slowly have mirrored regional sites created which then completely blocks all access outside the US and Cananda. These mirror sites are sometimes years behind the current US site, and reflect that many of the regional Nick affiliates are years behind the airing schedule. They are rarely updated with the tie-in/bonus videos that the US site is, and when they are, it's usually just plugging the latest episode that airs 8 months after it aired in the US. The worst offenders are the iCarly and Victorious tie-in sites, which makes watching the ending credits of their shows a bit infuriating...
Fortunately, some countries that don't have local versions of the tie-in sites can access the US iCarly and The Slap sites. What countries can access them, however, is yet to be found out...
However, there's still hope to access the US versions of the sites... Those in other countries just have to add "origin." before the whole site url.
The Hub. Good lord, The Hub... Considering that the content is mostly owned by Hasbro themselves, you'd think they'd make the video clips on the site available internationally to promote the toys. But noooooo, it's only available to the US. This is especially rage inducing in certain parts of the world where you can't get said shows due to the stupidity of the local pay TV providers. Physical transmission? Not happening either—the channel is not available outside of the US.
As of current, there's no Philippine Feed of Disney Channel. Not to mention there's no South East Asia version of Disney XD (Well, Malaysia and Singapore has it, but the rest of the region? eh...). Well, out of the 4 international youth channels in the Philippines, only three (Cartoon Network, Nickelodeon and Animax) have Philippine feeds separate from other countries' versions.
On the other hand, not everyone who lives in a country with regional feeds likes having one either, due to the feed being full of "hijacked" programming (read: local shows that are not by the company and shouldn't be on the channel in the first place, but are injected into the feed for no good reason) or even censorship (i.e. Animax Malaysia has a lot of the more risque anime exorcised and replaced with more reruns when said anime is airing in other markets).
The generic feed though, might be a bit subjected to Network Decay because despite being for Asians (and shared by the entire region), The feed still acts like Malaysians and Singaporeans still have more say on the feed than Thais, Filipinos, Indonesians and Vietnamese (One example: Christmas 2009's So Syok Holidays's promo was only open toMalaysians and Singaporeans than to the whole region, not to mention the main feed is near to act like the Malaysian feed (because recent months show that the main feed is now a dumping place for Malaysian content the other countries don't want anyway), one show is with subtitles instead of dubbed.) So yeah.
Speaking of Animax, that channel has yet to be available in North America.
Speaking of the aforementioned Disney Channel above, Ever wished to have a complete boxset of any Disney Channel Original Series in North America? Sadly, they're only available outside North America, in regions 2, 3 and 4, so the only way to watch these is both buying a region-free player and importing them. Only Lizzie McGuire and Hannah Montana had complete boxsets (but full seasons only though)—Season 1 for the former and seasons 1 and 4 for the latter available in the US.
There are still countries in the world where Google doesn't offer Google Play Store access outside of just apps. Meaning: No music and movies for you! (And if you're in China, no apps for you, even!note This is more due to the Great Firewall, though. Google has recently started to negotiate with the Chinese government for a way to provide the Google Play Store in China.)
Likewise, Microsoft's Windows Music and TV/Movies store, after being made available worldwide with the launch of Windows 10, is becoming unavailable again in a lot of parts of the world with the launch of the Fall update of Windows 10.note It is possible to trick the system into thinking that you're in an area that these stores are available in by editing the regional settings, which is also how you're able to access Cortana from outside of a supported region. But users could access everything in the store with their correct region when Windows 10 first launched. However this was changed with the Fall update. Many users feel that Microsoft has tricked them into upgrading to Windows 10 because of the fact. Additionally, this move has the side effect of shutting down the Groove music player as well...
THE BRIAN BLESSED ALARM CLOCK APP FOR IOS AND ANDROID. What better way to start your day BY GETTING YELLED AT AND INSULTED BY THE LARGEST HAM IN THE WORLD? Sadly, if you live outside the UK, YOU'RE NOT GOING TO BE ABLE TO GET IT, PERIOD.
If you happen to be in North or South America (especially USA) and you are unable to watch any video on TVP's website (including their own content) then you should thank to Spanski Enterprises who currently owns note (due to the 1994 Agreement signed between both companies and its later addendums) the exclusive TV/Internet/mobile rights to TVP Polonia content (including shows owned by TVP) in those aforementioned territories until at least the end of 2019 (!). note And even then, according to an interview, there's a clause that provides a possibility to extend the agreement into another decade. Because of this there's currently limited (if any) chance that any show to which rights are owned by TVP would reach the Americas outside the showings on TVP Polonia channel.
BBC Entertainment Asia became unavailable to Malaysia in December 2015 (This isn't the first time, the Channel was unavailable in Malaysia between 2009 and 2012 either). However, the drop happened during the initial run of Series 9 of Doctor Who- anything after The Zygon Inversion has not aired in the country. Both cable providers in the country and BBC Entertainment themselves have been unapologetic, and Malaysian Whovians are becoming frustrated and annoyed. It eventually surfaced that BBC Worldwide intended to shut down BBC Entertainment by April 2017 and replace it with BBC Brit and BBC First.
Netflix once had the dubious honor of coming in second place in this entry coming in right after Hulu. The service wasn't available in East Europe, Africa and the Middle East, and most of Asia (Japan is the only exception). Strangely, they were also not available in half of the EU, including Spain and Italynote as of November 2015, Netflix is now available in Portugal. In 2011, they even stated that they will not bother with New Zealand due allegedly sub-par Internet connections and data caps(egregiously, something that even exists in their home territory, North America). However, after what can be described as the largest Internet Backdraft of the millennium with many of New Zealanders pointing out the hypocrisy, they've eaten their words and launched the service in New Zealand. The aversion occurred at the start of 2016, when Netflix launched a surprise announcement at the 2016 CES that they're now available literally worldwide. The only countries that can't get them are Crimea, Syria, North Korea and China, the former 3 due to US sanctions, and the latter one being, well, China.
Amazon Video looked like it was quickly priming itself to take Netflix's place in the No Export for You list. The service was only available in the Americas, the UK, half of Europe, Japan, and India. They also have some highly-desirable exclusives, thanks to having their own production company. In mid-2016, rumor started spreading that they are planning to go global by 2017 in a bid to take on Netflix - due to the The Grand Tour cast mentioning on social media that the show will be available in over 200 countries worldwide come December 2016, followed shortly later with a suspiciously timed press release from Amazon claiming that they'll be rolling out localized webstores in Asia-Pacific countries by early 2017). Then, on December 13th, 2016, it happened- Amazon's streaming service went global, true to the words of the crew of The Grand Tour. Overnight, over 200 countries gained access to a library of Amazon original content, including The Grand Tour and Creative Galaxy. However, global coverage is weak at this time, with only a small sampling of shows and movies available compared to the other countries which got access earlier. Nonetheless, the outlook is bright and many are expecting more content to become available in time. Amazon is even giving these countries a lower Prime subscription cost to compensate for the lack of content. Global subscribers also need to use a different URL to access the content as opposed to those in countries where the service was launched earlier. While it's technically a bump-up from No Export for You to Bad Export for Younote The service is notably lacking in shows compared to the US, UK, German, Austrian and Japanese website, plus shows are only often added months after the main 6 market gets them, it's better than nothing. Plus the subscription fee is just half of that of the US' Amazon Prime.
