Wiley had bought Frommer's in 2001, but the travel publishers dates back to 1957, when Arthur Frommer wrote a travel guide for cheap Americans in Europe. That one title later grew to several hundred titles currently in print as well as websites, apps, and more.
This acquisition is going to be a good complement to Zagat, which Google bought last year for $151 million, as well as ITA Software, which Google also. You might not have heard of the ITA deal; this is a co0mpany that provides data services to travel websites.
So it looks like Google wants to own both the system displaying the data as well as the info on your screen. That's not what you'd expect from a search engine giant, but then again they do get most of their income from advertising. They can always slap ads up next to the travel content they now own.
