For months, fans have been demonstrating at Bundesliga games with banners out of worry that the league would be pressured by an investor to alter the competition's structure and prioritise TV viewers above the supporters present in the stadiums. The fan organisations claim that the Bundesliga's heavy emphasis on Germany's raucous audiences and full stadiums is their "biggest weapon" in marketing and that their silent protest would turn more heads. The demonstrations started when the top two men's football teams in Germany decided, by a slim margin, to move forward with talks to allow an investment firm to purchase a portion of future TV and marketing revenue in exchange for a one-time payment. The league states that there are "several interested parties" and that the stake would be limited to 8% over a 20-year period.
