NEW YORK ( TheStreet) -- Popular searches on the Internet include Nissan ( CAT) as the carmaker announced the revival of its Datsun brand but not for developed markets. Nissan said it will instead focus on emerging nations where the most growth for affordable, stylish vehicles is expected. Beginning in 2014, nations like India, Indonesia and Russia will receive the Datsun brand, though the specific offerings will be customized for each market. Two models will go on sale within the first year in the three nations, with an increased variety of vehicles available within three years. The new vehicles will be entry-level cars. The Datsun brand is being revived three decades after it was retired. It debuted in Japan in 1932 and in America more than 50 years ago. Caterpillar ( CAT) is also trending after announcing plans to expand production in China. The world's biggest heavy machinery maker said it would increase hydraulic excavator production by 80% in the country and open a new facility in 2016. The company also has plans to begin production of wheeled excavators at Caterpillar Xuzhou Ltd (CXL). Caterpillar calls CXL its manufacturing flagship in China. It has 17 facilities in the country, with nine more being built. China is a key factor in Caterpillar's expectations for record sales and profit this year. The company said it has a growing customer base in China, which is fueling its expansion plans. Saudi Arabia is a popular topic on reports there may be Saudi women competing ithe Olympics for the first time at the London Games. A Saudi Arabian newspaper said that Crown Prince Nayef has approved plans for the country to send female athletes to the Games. The heir to the current king has reportedly given approval that women will be able to participate in sports that "meet the standards of women's decency and don't contradict Islamic laws." The conservative Muslim country has never included women on its Olympic teams; neither have Qatar and Brunei. The chatter on Main Street (a.k.a.
