On Tuesday, Pfizer (NYSE: PFE) stepped into the earnings spotlight, announcing a higher third-quarter profit compared to last year. The pharmaceutical firm earned 43 cents per share, or 51 cents per share in adjusted earnings. A year ago, PFE earned 34 cents per share before item exclusions. The Street expected PFE to report third-quarter earnings of 48 cents per share excluding items.

Quarterly revenue checked in at $11.62 billion, 3% lower than last year's third-quarter revenue. Revenue was pulled roughly 5% lower due to unfavorable foreign exchange rates.

Google (NASDAQ: GOOG) had a killer product years ago after launching the awesome Google Earth software product for free to the masses. Many of us wondered (again) how the company was going to make money while giving away such great products. Recently, Google launched an enhanced, fee-based version of Google Earth that answered this question.

It comes as no surprise that one of the world's largest advertising companies (yes, Google) would leverage the globally known YouTube video-sharing site into many of its other properties as it experiments with adding advertisements into videos hosted there (in them, before them, etc.). YouTube has to be worth its billion-dollar asking price, after all, and it seems natural to let Google Earth users enjoy video clips from areas across the globe. Visit Africa on Google Earth, for example, and you may see links to YouTube videos on safari expeditions.

Google Maps already has this kind of integration. Search for an address, and you'll be presented with text links to nearby hotels, eateries, etc. The same goes for Google Gmail users. If Gmail senses that an incoming email deals with travel, it will supply travel links next to that email as you read it. Integrative and context-sensitive advertising is where the future of marketing is, and Google knows this. Video integration is only the latest step.
