Twitch has rolled out their new advertising system that was announced at TwitchCon 2019 in San Diego! All non-affiliate, non-partner streams now have NO ads! Pre-roll ads can be disabled by partners and affiliates by running periodic ad breaks. Every 1 minute ad disables pre-rolls for 20 minutes and every 30 sec ad disables them for 10 minutes. You can automate these ads using sites like Twitch Auto-Ad, bots like Nightbot, or applications/devices like Elgato's StreamDeck. Definitely a step in the right direction but more is needed!
