3 Top Tech Stories This Week: Facebook New Newsfeed, Google Overtakes Apple, and Blackberry Invades the U.S.

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

1. Facebook (META 0.72%) 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 (GOOGL -1.19%) surpasses Apple (AAPL 2.22%) 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 (BB 0.88%) 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.
