Which is why I said most companies with large bandwidth costs do not become profitable. YouTube eventually is one notable, glaring exception. But even they took years, billions of dollars in infrastructure investment and losses on bandwidth, access to a massive existing base of advertisers that already trusted its parent company, and arguably the best monetization team in the history of capitalism to achieve profitability.
Netflix and maybe Hulu are also profitable, but they are paid services which is a different beast. No reason that Twitch couldn't have paid/free tiers like Hulu someday though.
