#6 Yahoo

The company stumbled in to a deep well of loss previous year, and then Yahoo hired Marissa Mayer as CEO in July. Thanks to her now there are good working conditions for the employees and also she launched a redesign of the company’s email services and its photo-sharing service Flickr, the initiative which is getting company some economic mileage. However the company’s earnings fluctuated throughout the year, but they were up in the third quarter and are expected to have been up again in the fourth. Can Mayer lead the company to its glorious old days in the coming time? You have to watch it closely though to know.

#5 Twitter

Twitter seemed to be having good revenue gains in previous year. This online social networking and microblogging service had 100 million monthly active users in October 2011 which grew to 200 million in December 2012. And 70 percent of those tweeting actively live outside the United States. Max Wolff, a senior analyst at Greencrest Capital, told Bloomberg that if Twitter goes public in 2014, it could be valued at as much as $11 billion; the only thing Twitter has to do is get the number of users to match that estimated mark.
