The Mobile World Congress was held this week, with some of the hottest offerings from companies like Nokia ( NOK), Samsung, HTC, Asus, and Huawei. One key trend this year was companies trying to pack more features into their offerings without significantly raising prices amid a weak global economy. There was, however, innovation on show at the event, as evidenced by Nokia's attempt to revolutionize smartphone camera technology and Samsung's buzzed-about "projector phone."
Yelp ( YELP) went public on Friday, pricing its offering of 7.15 million shares above range at $15 each, raising $107 million. Yelp, which compiles reviews for local businesses, has seen its revenue grow sharply, from $25.8 million in 2009 to $83.3 million in 2011, an increase of nearly 300%. Losses, however, have continued to grow as well. Yelp's losses widened to $16.9 million in 2011 from $2.3 million in 2009. Yelp is highly dependent on Google ( GOOG) as a "significant source of traffic" but that could end if Google decides to promote its own properties. "Our success depends on our ability to maintain a prominent presence in search results for queries regarding local businesses on Google," Yelp said in its S-1 filing. Yelp shares finished up 63.87% or $9.58 above their IPO price, to close the day at $24.58. Interested in more on Yelp? See TheStreet Ratings' report card for this stock.
