Nielsen says it's going to increase the sample sizes in local TV markets, bringing more stability and accuracy to TV ratings.

The company also says it's going to add meters to 14 markets that were diary only.

Basically what this means is Nielsen now has some competition from Rentrak, and they realize they're going to have to start actually producing results, instead of just counting stations' money.

If you're bored, there's a lot more 'nielsen-speak' in Multichannel News.
