(CNN) - Apparently a lot fewer people are drinking milk these days, according to a Wall Street Journal report.
Citing U.S. Department of Agriculture data, it reports milk consumption in the U.S. has plunged nearly 30% since 1975.
Meanwhile, sales of yogurt, cheese and other dairy products have gone up.
Now, dairy companies are working to rev up milk sales again, hoping to attract busy families with new packaging sizes and styles.
They're pushing smaller, convenience-sized packages and varieties for people who work out, such as milk with added protein.
