The Yomiuri Group's Integrated Management
The Yomiuri Giants have been positioned as a core business of the Yomiuri Group, which boasts Japan's largest-circulation newspaper, the Yomiuri Shimbun, and the commercial broadcasting key station Nippon Television Network. This integrated management structure of newspaper, television, and baseball team created an overwhelming media dominance unseen among other professional baseball teams. The Yomiuri Shimbun prominently featured Giants game results and player information in its pages, while Nippon Television secured exclusive prime-time broadcasting of Giants games. Through this structure, the Giants functioned not merely as a professional baseball team but as an advertising vehicle for the entire Yomiuri Group, simultaneously driving newspaper sales and television ratings. Even when other teams' parent companies had media operations, none could match the influence of the Yomiuri Group, which controlled both a national newspaper and a key broadcasting station. This integrated management structurally undermined the neutrality of professional baseball reporting.

Giants-Centric Broadcasting
From the 1960s through the early 2000s, terrestrial television baseball broadcasts were almost entirely monopolized by Giants games. Led by Nippon Television, commercial broadcasters competed to air Giants home and away games, while opportunities for Pacific League games to receive national broadcast coverage were extremely limited. In the 1980s, over 100 Giants night games were broadcast annually, while Pacific League national terrestrial broadcasts were virtually nonexistent outside the Japan Series. This broadcasting disparity had a severe impact on Pacific League teams' name recognition and fan acquisition. The lack of television exposure directly led to decreased sponsor revenue, weakening the financial foundations of Pacific League teams. Consequently, the Pacific League's financial crisis, symbolized by the dissolution of the Kintetsu Buffaloes, was also a structural consequence of the Giants-centric broadcasting system. The disparity in broadcasting rights fees cemented the revenue gap between the Central and Pacific Leagues, hindering the overall development of NPB.
Information Control and Public Opinion
The sports pages of the Yomiuri Shimbun overwhelmingly favored the Giants in terms of coverage volume compared to other teams. Giants victories were prominently reported on the front page, while defeats received minimal coverage, and other teams' achievements were routinely relegated to the margins. This reporting stance instilled in readers the perception that professional baseball equaled the Giants, artificially expanding the Giants' fan base. Furthermore, in reporting on institutional reforms in baseball and other teams' management issues, the Yomiuri Shimbun tended to adopt editorial positions favorable to the Giants. During the 2004 baseball restructuring crisis, the Yomiuri Shimbun was noted for advocating a single-league system and publishing critical coverage of the players' union strike. Similar tendencies were observed in Nippon Television's news programs and sports coverage, revealing a structure across the entire Yomiuri Group that shaped public opinion in the Giants' favor. This media bias has been a target of criticism among professional baseball fans as 'Yomiuri's information manipulation.'

Declining Ratings and the End of Giants-Centrism
Entering the 2000s, terrestrial television ratings for Giants games plummeted. Ratings for Giants broadcasts, which had commonly exceeded 20% in the 1990s, fell to single digits by the late 2000s, and the number of terrestrial broadcasts was drastically reduced. Behind this ratings decline were the diversification of entertainment and the spread of the internet, as well as viewer fatigue with the Giants-only broadcasting model. Ironically, the Giants-centric broadcasting system itself accelerated viewers' disengagement from professional baseball. Meanwhile, the Pacific League launched its own marketing strategies following the 2004 restructuring, cultivating new fan bases through the Pacific League TV streaming service and enhanced fan services by individual teams. The spread of satellite broadcasting and internet streaming expanded viewing options independent of Giants games, and changes in the media environment hastened the end of Giants-centrism. However, the impact of decades of Giants-biased broadcasting was significant, and it took considerable time for Pacific League teams to stabilize their financial foundations.
