Kicking of Super Tuesday today in the United States, Metro editions around the world are using CNN content for the U.S. elections. Some content will even be exclusive for Metro, Newspaper Innovation reported Tuesday.

Super Tuesday is the day when nearly half the states in the United States participate in primary elections, selecting delegates to national conventions, where presidential candidates for each party are officially nominated.

The joint effort strengthens Metro and CNN's global brands, according to Newspaper Innovation.

For example, the Dutch Metro featured a two-page special today, explaining the U.S. primary system with an interview given by CNN's Richard Quest.
