Snapstream is an enterprise-level TV monitoring service. It's used mostly by news organizations and companies to keep an eye on what's happening on television every night, looking for a certain piece of video or bit of text or speech (the Daily Show famously uses it to keep track of all of that news footage John Stewart makes fun of every night). And despite its popularity, it's only been available on Windows -- until now.
Unfortunately, there's still not a dedicated Mac client, but there is a new web interface that Macs can access and use through the browser. The browser client will do everything the full client can, which means even users on Macs can search through TV broadcasts and find what they need.
Users can grab that video and transcode it on the server off to a more web-friendly format. If your company uses Snapstream (or has been thinking about using it), but was waiting for a Mac client, now's your chance.
