According to the Basler Zeitung, the Swiss Post bought the Swiss search engine search.ch in order to offer an all-embracing range of online services. They already offer email and e.g email-to-snailmail services.
That's a very interesting development for a traditional institution with their national monopoly.
There does not seem to be an official statement by the search engine guys yet, but you can read the statement of Swiss Post. I guess the Bernhard Seefeld blog -he's one of three associates of the company and probably quite wealthy by the time- will soon have enlightening explanations, too.
