This needs virtually no explanation. It's a chart of the frequency of the phrase "Housing Recovery" in news articles over the past 5 years.

The chart was created using the WORD function on Bloomberg, which lets you chart the frequency of various words or phrases over time, and which draws on a wide range of news stories that go through the system.

While this is certainly a second order datapoint (the real data has been hinting at this for awhile) the prevalence of this talk in the media presumably has nice follow-on benefits for buyers thinking about getting into the market.
