This is typical Intel
Intel have a long history of building up, or buying, a business then dumping it.
It has happened with numerous microcontrollers: 8051, 960 and others.
It has happened with their memory products.
It has happened with their StrongARM/Xscale line.
It has happened with thei USB chipsets.
It has happened with various companies they bought then sold (eg. Dialogic).
It is no wonder that nobody wants to build their chipsets into embedded products any more.
They normally dump non-core businesses when they're getting beaten up and expect to face angry shareholders, so selling off the TV biz suggests they expect to be mauled by the shareholders for all the screwing around in mobile and the hammering they continue to get from ARM.
