Vitrue (Oracle, $300 million)
Involver (Oracle, undisclosed)
Efficient Frontier (Adobe, $400 million)
Buddy Media (Salesforce, $689 million)
Wildfire (Google, $250 million)
Next up, HootSuite?
If you assume they were notified of the change in early 2012, and the change happened in March/April, and a deal of this size taking a few months to close, you can see how this deal (and the Buddy Media one) are likely directly related. The change also coincides with WF and BM both announcing ad-related pivots the day before Facebook announced their Timeline change (source: http://www.marketwatch.com/story/wildfire-announces-new-capa... and http://www.marketwatch.com/story/buddy-media-announces-brigh...).
The Pages change destroyed many companies. The week that the change was forced, I took a screen shot of the top app losers on socialbakers. Check it out yourself: http://i.imgur.com/C3zSQ.png . BandPage, for example, lost 90% of its traffic in 60 days. Wildfire apps saw their user base gutted as well. I remember looking up the stats for a few of their apps a month later and saw their app install base had fallen huge double digit percentages. It's hard to see exactly how companies like WF were impacted, but I think the Timeline change gutted their unstoppable growth and forced them to exit while things were still looking bright.
And this, in my opinion, helps explain why they took a relatively small exit of $250M (given the larger $689M of BM).
That's my guess at the situation.
( Edit: The reason I have this info handy is because I looked into this in depth a few months back: http://www.michikono.com/2012/03/22/facebook-is-okay-with-hu... )
BM seems more focused on big brand/Fortune 500 customers with a big focus on analytics. From what I read they were making a lot of money too.
Wildfire seemed like more of a SMB tool.

How is that a bubble? Who is getting fooled out of their money?
