The ePUB format is probably the most common of all the formats and is widely supported across all platforms. Most eReaders like Apple’s iBooks, Barnes & Noble’s Nook, Adobe Digital Editions, Aldiko on Android among others (nearly 300) support .epub files. Amazon Kindle so far does not, but it might change very soon. The ePUB format is an open standard. That means it is free and publicly available though there are specific rules for its usage. The ePUB standard is maintained by the International Digital Publishing Forum (IDPF), a global trade and standards organization.
The Mobipocket or mobi eBook format is another open standard for eBook publishing. It was bought by Amazon. It is also cross-platform. eBooks in this format can have the .prc or .mobi extension.
