News Corporation Chairman Rupert Murdoch was interviewed last week by Fox Business Channel. During the interview Murdoch blasts Google for stealing his content and talks about how tablet devices will reinvigorate the advertising industry for new media.
As for the iPad, Murdoch states, "...all media will be coming to the iPad whether it be music, or books, or newspapers or movies" and contrasts it with the "black and white" Kindle. He imagines reading a newspaper article with a photograph in it and just touching the photograph to watch it become a video.
He goes on to say that the iPad is physically "small to start with" but says "there'll be more iPads" implying that they'll eventually come in larger sizes. Even though he is one of the most important people in the media world, Murdoch's comments are most likely conjecture and not inside knowledge. Skip to 1:45 for the iPad mention.
