Somewhere between the frenetic antics of Cookie Monster and the violent baton swings of a late-night conductor's symphonic concerto, PBS is changing.

Sure, you may not notice it by simply tuning in to PBS on your television set. It's something that you will only catch at Earlier this year, the Public Broadcasting Service began broadcasting Google (NASDAQ:GOOG) text ads on its site.

Thanks to Google's breadth of advertisers and its contextual prowess, PBS is getting sponsors that are pretty spot-on. For example, going to the PBS search page, I found an assortment of ads for things like kid haircut kits, science class planning, and a quiz to determine if you're a slacker mom.

Today's show is brought to you by the letter Google
If advertising on PBS seems odd, it's because the company prides itself on being a non-profit group consisting of 348 public television stations. They don't air "advertisements," if we go by the conventional definition.

However, good luck avoiding the advertisements that come in other forms like "generous grants" from corporate sponsors. Then we have the pledge drives where shows are interrupted so we can all learn how to get a Clifford duffel bag with a modest $100 contribution.

Fundraising? Grants? Pledge drives? Tapping into the Google gold mine to help subsidize website costs shouldn't feel any different, but it has become a sore spot for PBS. According to the Broadcasting & Cable blog, PBS is now emphasizing disclaimers beneath the Google ads to distance itself from Google's role in providing the ads, as well as from the content of the sponsors themselves.

That's funny. When I see a McDonald's (NYSE:MCD) ad when my son is watching PBS, I don't see a disclaimer pop up warning me about going for fries instead of apple slices in my son's next Happy Meal.

I know. In an ideal world, PBS would be quietly bankrolled by charitable foundations. But the world doesn't quite play that way. Even a generous gesture like Oracle's (NASDAQ:ORCL) Larry Ellison agreeing to donate $115 million to Harvard can be notoriously pulled off the table.

Google works for because Google works. Period. As bad as things have gotten for Time Warner's (NYSE:TWX) America Online, the one bright spot has been the healthy growth in AOL's online advertising, and investors can thank Google for a lot of that.

If anything, I'm surprised that more non-charitable organizations haven't jumped on the Google AdSense bandwagon. Yes, the groups can't endorse every single sponsor, but Google's program does allow the luxury of filtering out certain advertisers. Google also has editorial standards that it goes by in accepting spots in the first place. Besides, do charities question every buck that is donated? The incentive to follow a paper trail and return any blood money seems limp and half-hearted at best.

Faith in hope and charity
I predict that in five years you are going to see a lot more Google ad blocks online. Yes, I'm also opening up that invitation to rival products like Yahoo! (NASDAQ:YHOO) and Microsoft (NASDAQ:MSFT). I can't recall a church bulletin that wasn't loaded with business card ads in the back, so it's really just a matter of time before more religious and charitable institutions pad their fundraising efforts by embracing the simplicity of online advertising.

Oh, I'm sure that there are probably dozens of forward-thinking religious institutions out there that have preachers blogging away every week alongside perfectly targeted text ads. Google and Yahoo!, and eventually Microsoft, make it so easy that it's almost as if someone is leaving money on the table if they don't pursue that as a strategy.

Churches and regional charities also provide a localized focus, and that's even sweeter gravy for local merchants and service providers that will pay well for quality leads.

So don't be ashamed, PBS. You're doing the right thing. Maybe it will mean shorter pledge drives in the future. At the very least, it may mean fewer Clifford duffel bags to unload.
