I still thought Opera had advertising in the interface, and had actively avoided using it. After your comment, I read their 1Q report -- apparently they're working on back ends to compress web data to send to their Opera mobile browsers (less bandwidth), along with a Google partnership for the desktop search (and other ventures).
I wondered how long it would take for streaming movies to get ads embedded within, or around the display frame. Combine this innovation with the picture recognition advertising technology, and preference targeting, and I'm afraid the synergy of the underlying revenue stream would be insurmountable.
Would Dish Network or DirecTV have prior art on some aspect of this? They both currently have integrated ads within the program guide. Or the TVGuide channel, with the incessant video ad at the top? Did someone think to include an ad frame on the new TVs that connect to the internet and show videos and web pages? How about Microsoft's and Dish Network's WebTV? Video games with a "pay to continue" timer?
