Roku, the US-based content streaming platform and device maker backed by media conglomerates Hearst and News Corp, has added $45.5m to its war chest, Variety reported on Friday.
The fresh funding was revealed in a regulatory filing last month, but a company spokesperson would only confirm that Roku raised capital in late 2015.
Founded in 2008, Roku produces a set-top box that enables viewers to stream free and paid content to their televisions. The company is also increasingly focused on partnering hardware manufacturers that integrate the technology straight into their television sets.
Roku is hoping to expand its list of content partners, which includes broadcasters Time Warner Cable and Sky, in a bid to get them to replace traditional set-top boxes with Roku’s technology.
The company has raised approximately $200m to date, having secured $25m from unnamed investors in 2014, when it was reportedly considering an initial public offering worth up to $150m.
Broadcaster BSkyB and its parent company News Corp backed a $45m series E round in 2012 alongside Menlo Ventures, Globespan Capital and one unnamed investor.
Both corporates returned in 2013 for a $60m round led by financial services firm Fidelity also backed by Hearst. Online streaming service Netflix has also been reported as an investor in Roku.
