I don't believe that was the focus. I think it's an important point, though, because news has great social value, but in many cases it doesn't have that much economic value.
As Richard mentioned, it's perhaps less than 2% of the queries. They tend to be the least monetizable queries—in other words, the queries that are less likely to have an ad next to them. If you do a query for a digital camera, you will see a number of ads for that, but if you do a query for how tall Mount Kilimanjaro is or what's going on in the Canadian Parliament today, you probably won't see many ads, and very few people will click on them. It's just not a very strong signal of commercial intent.
News has never been primarily about economic considerations for us. It's more a question of how we can best provide a range of information.
