The rise of the LP: the politics of diffusion innovation in the recording industry
研究了1951年45转单曲和33转专辑标准化如何迫使唱片业重新思考营销策略，通过1955-1979年专辑和单曲排行榜数据发现行业倾向于次优、风险规避策略，LP的成功可能并非公司控制的结果。
This article investigates how the standardisation of the 45 RPM single and 33 RPM album in 1951 forced the recording industry to rethink their marketing strategies. The industry’s focus on weak unit strategies and capitalisation on the emergent artistic aesthetic are evaluated. To establish correlations between strategies and the popularity of singles and albums between 1955 and 1979, OLS models were generated using large datasets on chart performance of albums and singles. This study concludes that the industry tended toward sub-optimal, risk-averse strategies, and that the LP likely succeeded despite record companies’ efforts to control their products and messaging.
