BBC News: Yahoo CEO Marissa Mayer said the company has made “great progress” despite reporting a loss for the second quarter. The search and advertising firm reported a net loss of $21.6 million in the quarter, but said revenue rose 15 percent to $1.04 billion. “Yahoo’s transformation continues to make great progress,” said Mayer. The company’s boss, who has been at the helm for three years, has been steering it away from advertising tailored to desktop computers towards mobile and video ads to increase sales.
