What are some unknown companies in the digital media / entertainment / streaming industry?

I'm not sure exactly what I'm asking, but something in the realm of:

• NFLX
• DIS
• PARA
• SONY
• AMZN
• CMCSA
• GE (partial ownership in Peacock?)
• NLSN
• ROKU
• AAPL

Maybe some other adjacent things like projectors, misc component parts, Roku box competitation, software(?) etc…

edit: maybe theater equipment?
