Change to Google Policy Regarding Use of Your Personal Information

The following is cut from a desciption by Google of their new policy regarding personal information.  I've highlighted the important sentences.

How your Profile name and photo may appear (including in reviews and advertising)

We want to give you – and your friends and connections – the most useful information. Recommendations from people you know can really help. So your friends, family and others may see your Profile name and photo, and content like the reviews you share or the ads you +1’d. This only happens when you take an action (things like +1’ing, commenting or following) – and the only people who see it are the people you’ve chosen to share that content with. On Google, you’re in control of what you share. This update to our Terms of Service doesn’t change in any way who you’ve shared things with in the past or your ability to control who you want to share things with in the future.
Feedback from people you know can save you time and improve results for you and your friends across all Google services, including Search, Maps, Play and in advertising. For example, your friends might see that you rated an album 4 stars on the band’s Google Play page. And the +1 you gave your favorite local bakery could be included in an ad that the bakery runs through Google. We call these recommendations shared endorsements and you can learn more about them here.
When it comes to shared endorsements in ads, you can control the use of your Profile name and photo via the Shared Endorsements setting. If you turn the setting to “off,” your Profile name and photo will not show up on that ad for your favorite bakery or any other ads. This setting only applies to use in ads, and doesn’t change whether your Profile name or photo may be used in other places such as Google Play.
If you previously told Google that you did not want your +1’s to appear in ads, then of course we’ll continue to respect that choice as a part of this updated setting. For users under 18, their actions won’t appear in shared endorsements in ads and certain other contexts.
For greater control over your experience with ads on Google, you can also use Google’s Ads Settings tool to manage ads you see. Learn more.
