It looks like mega-retailer Walmart might be looking to get into the growing streaming stick market with a device called the Vudu Spark that was reportedly leaked from the FCC Website. The gadget, which would compete head-to-head with other popular devices in the category, like the Google Chromecast, Amazon Fire TV stick, and Roku Streaming Stick, appears as though it’s strictly tied to the Walmart-owned Vudu service, simply making it easier to access Vudu on the big screen over Wi-Fi.
