One key consequence of these TVs is the elimination of boxes, such as the Playstation 3, that previously served this purpose.  In their first XBR9 TV, Sony took the interfact software from the PS3 and installed it in the TV along with key features such as streaming media from a local PC, Amazon on Demand and Yahoo Widgets.  Here is one of the first reviews:

CNet review of the Sony KDL-52XBR9 which includes Amazon on Demand (premium video delivered straight to the TV via broadband).

Review of the Yahoo Widgets which will add new types of services and applications to Connected TVs.

Mobile video has been around for a number of years, standing ready to break out.  Hulu, which took online TV mainstream with a consumer friendly site and familiar content, now plans an iPhone app which could have the same impact, according to Alley Insider.

It’s still too early to now the app’s exact capabilities and how more mainstream mobile video usage will truly impact marketing and communications (the mobile video related campaigns right now are small and experimental as compared to TV and Web video).  But it will be interesting to see what Hulu comes up with and if it has the same impact as their site.
