Eric Bleeker believes these are the top three tech stories of the week:

1. Facebook (NASDAQ:FB) redesigns its newsfeed to keep advertisements fresh. Facebook is putting adverts in the body of the newsfeed instead of in a banner to the side of the page. This should keep advertising revenue going.

2. Google (NASDAQ:GOOGL) surpasses Apple (NASDAQ:AAPL) for institutional  ownership. Google flies while Apple dries. Analysts are going gaga over Google, and hedge funds and mutual funds now own more Google than Apple.

3. BlackBerry's (NASDAQ:BBRY) new smartphone to launch in the U.S. on March 22.  Blackberry has launched its newest smartphone in a variety of other markets with differing results. Will the BB10 rescue Blackberry from oblivion in the U.S. market? The answer will begin to be known later this month.
