What happened to the Discovery Fit and Health Channel?

The Discovery Fit & Health channel was rebranded to Discovery Life in 2015**. This was a strategic decision by Discovery to focus on the "life" and "lifestyle" programming that was already popular on the channel. The new name reflected a shift towards more aspirational and inspirational content, while still offering some of the health and wellness programming that was a staple of the original channel.

So, the channel didn't disappear, it just got a new name and a slightly different focus!
