Airplay.
I saw the advert touting that functionality the other day.
My first reaction was; "Oh, Apple have included DLNA functionality so if I bought an iPad it would talk to my telly and media streamer. How nice[1] and better late than never.". Then I noticed the little box with an aerial on it hiding under the telly in the ad and the small print at the bottom of the screen saying; "Requires additional hardware....".
Cue total sense of humour failure.
Typical. Abso-bloody-lutely typical. Perfectly good standard method for achieving the same results, supported by most of the new kit on the shelves these days and Apple have to do it differently so they can flog you extra kit that you don't really need (Hey! More wires and plugs. Do I get a hole in the head with that too?). They should be shot. And cremated. And then shot again for good measure.
[1] Well, less "How nice" and more "meh" actually, but it's the thought that counts.....
