“…Despite the growing interest in the scientific community, all these topics have been studied primarily from the perspective of the platform owner, also known as the ‘keystone firm’ (Cennamo et al, 2018), and what the platform owner should do in order to successfully manage its network and generate profits (Kim et al, 2017). Additionally, a relevant amount of extant research already examined advertisers' and viewers' perspectives (Gawer & Cusumano, 2014; Gal‐Or et al, 2018; McIntyre & Srinivasan, 2017; Smith et al, 2012; Sashittal & Jassawalla, 2022; Lee & Watkins, 2016; Verhellen & De Pelsmacker, 2013; Hanna et al, 2011). When these complementary actors are considered, the emphasis is on how they can increase their innovation capabilities through the platform ecosystem (Boudreau, 2010; Parker & van Alstyne, 2017; Wareham et al, 2014), how they act as a source of external knowledge (Eckhardt et al, 2018; Kapoor & Agarwal, 2017; Srinivasan & Venkatraman, 2018), and how they spur the platform's growth potential through complementary products or services (Anderson et al, 2014; Venkatraman, 2004).…”
