LoveFilm

Netflix hopes its latest move doesn't turn out to resemble a British comedy. The video buffet operator introduced its streaming service in Ireland and the U.K. on Monday. And while overseas expansion is old hat for Netflix, this time, the challenges are bigger.

Amazon.com on Thursday announced it is buying Lovefilm, a European home-video distributor that some have called the Netflix of Europe. The deal will give the world's largest online retailer a stronger foothold in digital-video distribution. Will it buy Netflix next?
