AppleTV a loser? The only device significantly ahead of it in sales is the Roku (Amazon and Google's sticks are ~the same number of sales as Apple TV). But the market is pretty evenly split in sales and Apple still maintains one of the larger overall install bases for any of them (not the outsized winner it used to be there though of course). "Not being a de-facto monopoly" is hardly a loss.
Articles like http://www.recode.net/platform/amp/2016/6/10/11904942/google... seem to point to Apple TV being easily outsold by Amazon and Google.
Roku had $400 million in revenue in 2016[1] which includes content share while Apple TV produced a billion dollars of revenue back in in 2013 [2]. And Apple's margins are way higher than Roku's. Apple TV, while a self described 'hobby' by Apple (presumably when compared to iOS/Mac), was and still is a very successful product in a category it basically invented.
