debundesliga1-5, Exercise 1: Growing income

Model answer:

1. Shirt sponsorship: companies paid to put their names on shirts, giving clubs a steady income apart from tickets.
2. Television: broadcasters paid for highlights and later live rights, which brought money and a larger audience.
3. Higher revenue from larger crowds, merchandise and European competition.

Effects: clubs could pay higher wages and invest in squads and stadiums, but they became more dependent on sponsors and broadcasters, and the gap between rich and poor clubs could widen. Details should be checked.
