Facebook also announced its own camera app on Thursday, Facebook Camera for iPhone. The new app makes photo sharing easier, Facebook said, allowing users to share multiple photos at once, caption pictures, tag them and put their locations on them. This follows last month's announcement by Facebook that it's purchasing Instagram, a social networking app, which has many of the same features as Facebook's just-launched app. Shares of Facebook fell 16.5% this week to close at $31.91.
Investors punished Dell this week after the tech giant missed Wall Street's revenue and earnings estimates in its first-quarter results on Tuesday, citing a "challenging" economic environment. Dell earned 43 cents a share on revenue of $14.4 billion during the quarter. This was down from last year, when the company earned 55 cents a share on $15 billion in revenue. Analysts polled by Thomson Reuters expected earnings of 46 cents a share on $14.91 billion in revenue. Dell's second-quarter guidance was also weaker than Wall Street was expecting. Dell said it expects sales to come in between $14.69 billion and $15 billion. Analysts surveyed by Thomson Reuters are looking for sales of $15.42 billion. Shares of Dell plunged 15.5% this week to $12.46. > >> Bull or Bear? Vote in Our Poll
