Amazon has been making its presence known overseas lately, and now an article by All Things D indicates that the company's Android Appstore could be opening for business in Europe this summer. Amazon currently serves the United Kingdom, France, Germany, Austria, Italy, and Spain in the retail channel, and these could be natural expansions for the company's digital goods. The Appstore is available on nearly any Android device (provided it can sideload apps), meaning that if this rumor were to come to fruition, international Android users would finally have an alternative to Google Play.

The big question is whether Amazon's Kindle Fire will follow the Appstore into Europe. The Fire's forked version of Android makes it a lucrative silo for Amazon's sometimes exclusive digital content, creating a promising trojan horse from which to expand its sales into new markets.
