Check out these self-reported behavior changes, via Gravity Tank, a Chicago consultancy that surveyed 1,000 heavy “app phone users.” That’s defined here as people who used either Apple’s (AAPL) handset or Google’s (GOOG) G1 phone from T-Mobile. (Click chart to enlarge.)

Of course, you’ll want to take this with big bags of salt. Because I’m not sure how many app users were really using an “Internet Tablet” to begin with. And I don’t see how monkeying around with likes of Ocarina and The Moron List is going to cut down on your caloric intake.

But! The fact is that app users think they’re watching less TV, etc., which at least means they value that stuff less.

So if you’re in the media business, the implications here are clear: Shoving your stuff into a browser won’t do you much good in a mobile world defined by apps. And the smarter media executives I know are scrambling to adapt.

I talked to a network TV guy yesterday who told me his company was making “tens of millions of dollars” from mobile right now but that pretty much everything it has done to date–carrier deals, licensing pacts, etc.–will have to be rethought and redone in light of the coming app world. He’s going to have to move very fast.

And if you’re not convinced, here are some of the folks Gravity Tank interviewed for a parallel set of “ethnographic” studies. If some of them seem a bit too much like the “I’m a Mac” dude from the Apple ads, bear in mind that these are iPhone users who agreed to be interviewed on camera talking about their love of apps. So that’s going to come with the territory.

The latest: An announcement that advertisers who buy AdWords–Google’s main revenue engine–can now automatically buy mobile advertising, too. The company says AdWords buyers can choose to have their AdWords automatically show up on phones that support “real” Internet browsers like T-Mobile’s G1 phone and Apple’s (AAPL) iPhone. Here’s an example:

These ads will reach a relatively small slice of mobile phone users. But that population will increase rapidly, particularly if Apple really does start selling cut-price phones at Wal-Mart (WMT). Which means that Google (GOOG) really may be the first company to make inroads toward the supposedly-huge-but-so-far-mythical mobile ad market.

Release from Google’s Daniel Rubin:

Today, we’re announcing a new campaign-level option that allows you to extend the reach of your text and image ads to show your AdWords ads on the T-Mobile G1, the iPhone, and other mobile devices that have full (HTML) Internet browsers. This new option will now allow you to display your ads specifically on these devices, create exclusive campaigns for them, and get separate performance reporting. We hope this option will help you more effectively reach your audience with the right message at the right time.

G1 and iPhone ads have many of the same benefits as our standard mobile-format ads, such as allowing you to deliver mobile-specific calls-to-action and reaching your audience when they’re on the go. Showing ads on the G1 and iPhone also have additional advantages for your advertising. Users are performing a lot of searches on these devices, and searches are likely to go up during the holiday season. Last Christmas, the iPhone drove more traffic to Google.com worldwide than any other mobile platform.

Unlike standard mobile ads, you don’t need to format your ads for mobile phones to show your ads on the G1 and iPhone. Because the G1 and iPhone has full Internet browsers, you’ll be able to display your standard AdWords ads and landing pages on these devices without having to modify them.

With this new option, you’re opted-in to show ads on the G1 and iPhone, and you’re also eligible to show on additional devices that use full Internet browsers as these devices enter the market. If you want to change your settings to only show ads on G1s and iPhones or to not show ads on these devices, follow these steps.

If you’re running standard mobile ad formats, they won’t be affected, and they’ll continue to run on mobile phones with mobile (WAP) browsers.”

Apple (AAPL), Research In Motion (RIMM) and Google (GOOG) are duking it out for consumers’ smartphone dollars this fall. But here’s an early winner: Time Warner’s (TWX) AOL, which has just landed a giant contract to push Google’s G1 phone for the next two days.

Wireless carrier T-Mobile, which is selling the phone in the U.S., is launching a big push on AOL’s Platform A ad network today. It has agreed to buy a billion impressions today and tomorrow, reports AdAge.

Reporter Michael Learmonth talks to industry sources who think the buy could cost T-Mobile around $1.5 million, which would work out to a cost per thousand of $1.50. Ad folks I talk to think that number sounds high, and guesstimate that the CPM will be closer to the $1 to $1.10 range.

But no matter what the number is, the campaign will be a win for AOL. Anything approaching $1 million over two days will be well-received at the company, which saw ad revenues drop six percent in the last quarter.

And the fact that AOL can offer an advertiser a billion impressions in two days also points out how the ad network business is supposed to work: Gather lots of Web sites and offer their combined inventory to advertisers, who can buy a lot of eyeballs at a discount. Now AOL just needs a lot more of these, fast.
