Zoom can be great for webinars, yes, but it has its limitations. Zoom allows for view-only access and is a great communications tool for conference calls and screen sharing where a team of 100 people or less can also see each other and chat. Zoom has basic webinar features, however, if you're looking to hold a more advanced session with many more attendees than you may want to consider those like WebinarJam, Demio or Webinar Ninja.
