Masuda method
The Masuda method, also known as Masuda's method (Japanese: 国際結婚 international marriage), is a fan-made term which describes a way to easily obtain Shiny Pokémon in Generation IV and V. Rather than encountering Shiny Pokémon with a probability of 1/8192, Masuda's method lets players breed Pokémon of differing real-world geographical origin with at least a 1/2048 probability of being Shiny upon hatching.
It is named for Game Freak director Junichi Masuda, who programmed it into the Pokémon Diamond and Pearl. He documented the method in his blog[1], where he mentioned a way for "rare colored Pokémon's Egg [to] be found little easier." The mechanics behind this were discovered by Smogon.
Usage
The key to using the Masuda method is not to breed any two Pokémon, but to breed two Pokémon created in games of different languages. An egg resulting from such a pairing will have a higher likelihood of being Shiny. The most common way to arrange such a pairing is to use one foreign Pokémon and one from the game in which the breeding occurs, although the method will work in any game provided at least one of the Pokémon in the pair is from a language different to the language of the game cartridge.
There are a few exceptions to this basic premise. If both Pokémon are foreign to the cartridge but are both from the same language, then the Masuda method will not take effect. Additionally, if the player tries to breed one of his or her own Pokémon with a foreign Pokémon obtained through an in-game trade (such as the Meister's Foppa and Lt. Surge's Volty), then the method will also fail. In this case, it is because the two Pokémon breeding were generated on the same game and therefore in the same language.
A Pokémon traded internationally while still in its egg will retain the internal marking which recognizes it as a foreign Pokémon even though it appears to be native to the cartridge it was hatched in.
Some examples are illustrated below. Pokémon bred in circumstances which invoke the Masuda method and may be Shiny are denoted by their Shiny sprite.

Mechanics and reasoning
The Masuda method is possible because of an internal marker on each Pokémon which identifies their "home location", 0x17. If the game recognizes the two Pokémon in the daycare as having different home locations, then the chances of the egg hatching into a Shiny Pokémon will increase. In Pokémon Diamond, Pearl, Platinum, HeartGold, and SoulSilver, the odds will be increased by four times: from the usual 1/8192 to 1/2048. In Pokémon Black and White, the odds were increased again, to 1/1366. This is six times as likely as encountering a Shiny Pokémon in tall grass.
Reaction and purpose
From Generation IV onwards, trading with games from other languages became easier thanks to the Nintendo DS's ability to communicate through Nintendo WFC. Masuda's method was likely coded as incentive for players to use the GTS international trading services.
Though the odds of obtaining a shiny Pokémon are still fairly low, the chances have now been increased so significantly that players have touted it as a more reliable method than the Pokémon Diamond, Pearl, and Platinum's Poké Radar. Masuda's method is even more appealing, since it allows players to customize their team further, with specific egg moves and IVs that would be either unavailable or harder to obtain. However, when breeding with two foreign Pokémon, the 50% chance of passing down a parent's nature via an Everstone is not present.
