Russian is the main language of the 9th most populous country in the world. Russia is also number 6 in the world when it comes to purchasing power, meaning marketing towards Russian speakers is definitely a good idea.

Russian is the main language in Russia and Belarus, and an official language in Kazakhstan and Kyrgyzstan. Other countries that used to be part of the Soviet Union still consider Russian a sort of lingua franca.

Besides its prominence in Eastern Europe, Russian is also one of the official languages of the United Nations. It is the most commonly spoken language of the Slavic language group, with around 150 million native speakers. That is a lot of potential clients and customers, considering the economic power Russia alone has.
