Walmart's Vudu service will be dipping a toe in foreign waters for the first time, with a planned expansion that could see it landing in as many as 30 new countries. Mexico will be the first to get the service -- some time in June -- before it continues in a southerly direction toward other Latin American states. The rest of the expansion will cover Europe (including the UK and Ireland) and Asia, but won't happen until later on in the year. While Netflix has already beaten a path away from US shores, Walmart clearly hopes its strong retail presence (5000 stores in 26 countries) will help it earn more than just a tourist visa.
