From the 1980s onward, the major league game changed dramatically, due to the combined effects of free agency, improvements in the science of sports conditioning, changes in the marketing and television broadcasting of sporting events, and the push by brand-name products for greater visibility. These events lead to greater labor difficulties, fan disaffection, skyrocketing prices, changes in game-play, and problems with the use of performance-enhancing substances like steroids tainting the race for records. In spite of all this, stadium crowds generally grew. Average attendances first broke 20,000 in 1979 and 30,000 in 1993. That year total attendance hit 70 million, but baseball was hit hard by a strike in 1994, and as of 2005 it had marginally improved on those 1993 records. (Update: Between 2009 and 2017, average attendance hovered just over the 30,000 mark, with numbers falling into the 28,000s in '18 and '19. The 2019 season saw a million fewer tickets sold than the banner year of 2007, however revenues to major league baseball from media rights fees increased total revenue to $10 billion in 2018, a 70% rise from a decade before.)
