Television studios have “quietly” begun adding closed captioning to a small selection of the TV shows on offer in the iTunes Store, says “AppleInsider” (http://www.appleinsider.com).

Fox, FX, CW and ABC are among the studios that have added closed captions to TV shows on iTunes, the article adds. Specific shows include “Sons of Anarchy,” “New Girl,” “Switched at Birth” and “The Secret Circle,” though, in general, only the current season of these shows carries support for captions.

It’s not exactly clear when the first captioned TV shows arrived on the iTunes Store, but as late as last month, reports claimed that no TV shows on Apple’s digital storefront offered the feature, says “AppleInsider.” Most of the shows providing the closed-captioning are from the fall 2011 TV lineup and have only been added recently, the article adds.
