Eh, with that logic you could argue that all music streaming services are the same product with different front ends. Which, in a way, is kinda true…
Go existed for a few years before Now was released, and they were separate websites/apps. I’d say they qualify as different products. I would be interested to know if they shared any backend tech though. Would probably save a pretty penny if they shared a CDN.
