Actually, the funny thing is that there is no wizard TV or wizard video games. Just the newspaper and chess and exploding snap, whatever that is.
This was actually clever on JKR's part. There is no reason for a telephone or radio to be invented for communication. And without a telephone or radio, there's no reason to evolve into television. And all pictures are "motion pictures" to some extent, so I'd imagine that wizard movies would never be the same twice as the characters might have minds of their own.
In book 7 there IS a wizard radio. The kids listen to a pirate station to get the real scoop about what’s going on.
