Vizio updates its SmartCast TV software with voice commands and better search

It's no secret that many of today's smart TVs aren't really all that intelligent. Slow and unintuitive navigation and clunky user interfaces still plague this space, and consumers sometimes opt for some sort of set-top box, even when their TV has streaming apps built in. Fortunately, Vizio's smart TVs don't fall into that category, thanks in no small part to its user-friendly SmartCast interface — which just got a major upgrade.
