Digital video is a fast-changing arena.<br />YouTube, under CEO Susan Wojcicki who has empowered its engineers, is steadily rolling out products, updating existing platforms and making it easier to connect videos with audiences - and the advertisers that follow.<br />Amid the rise of video competitors including Facebook, Snapchat, Twitter, Vessel and Twitch, YouTube engineers have added support not just for vertical but also 360-degree video, created apps dedicated to popular categories like gaming and overhauled the company's primary mobile app to make it easier for people to find videos they want to watch.<br />To the potential chagrin of advertisers, they are also developing an ad-free service for people who would rather pay than contend with pre-roll and overlays.<br />However, YouTube is also doing things to increase the amount of time people spend watching ads.
