Only 8 percent of revenue from the NFL's pink merchandise to support breast cancer awareness actually goes toward cancer research, according to Business Insider's report.
The report shows that the league keeps just 1.25 percent from the sale of pink merchandise, handing over 11.25 percent to the American Cancer Society. But 25 percent of the revenue goes to the company that makes the product and 50 percent to the company that sells the merchandise. The most popular places to purchase NFL gear are on the online league shop and at team shops online and at stadiums.
Every October the league unveils head-to-toe pink gear - from socks, to towels and sweatbands - for players to wear and fans to purchase, all in support of breast cancer awareness. The league recently discontinued the use of pink penalty flags after deeming them too confusing for players.
