Set-top boxes are great because they usually just work, but the downside to this reliability is that adding functionality isn't a download away --- like on a PC. So if Microsoft wants to get Silverlight content on to set-tops it needs to work with the people who make the chips, and there's no one better than Broadcom
and Intel. In fact Broadcom powers more TVs, Blu-ray players and DVRs than anyone, but that doesn't mean Intel isn't trying to move in on that market
. Of course you'll never know if your set-top includes the Intel BCM7420 or Intel CE4100 series chips, but you will surely appreciate the additional internet delivered HD video (like the Olympics or Netflix Watch instantly).
