Pop, soft drink, soda or Coke—whatever you call it, you're probably drinking less of it.
Last year was tough on soda sales, which declined for the 10th straight year as consumers favor the healthier image of other drinks. Now heavy weights Pepsi and Coca Cola are getting hit especially hard, according to report by Beverage Digest.
The report, featured online by Fortune magazine, showed the total sales volume of carbonated soft drinks slid 0.9 percent from 2013 to 2014. Within that category, Coke posted a 1.1 percent drop in volume, and Pepsi saw a 1.4 percent decline.
Meanwhile, sales volume across the entire beverage industry, including non-carbonated beverages and water, increased 1.7 percent in 2014, according to Fortune. Within carbonated beverages, smaller players like Monster Beverage and Red Bull expanded their market share.
Despite declining market power, especially within the Diet Coke brand, Coca Cola remains the most popular soft drink in the U.S.— and posted modest growth as a company. Pepsi, Diet Pepsi and Diet Mountain Dew trail Coke in popularity and also posted declining sale volumes in the report.
