Discovery Inc. made a splashy presentation of an expanded programming lineup at its upfront Tuesday evening, touting the breadth of the lifestyle niches the cable group serves after acquiring the parent company of Food Network, HGTV and Travel Channel for $14.6 billion earlier this year.

Discovery president-CEO David Zaslav opened the session at Alice Tully Hall by talking up the appeal of the company’s “functional content” as good counter-programming at a time when the TV world is awash in scripted programs.

“We don’t do red carpet, we don’t do Hollywood stars,” Zaslav said. “We pretty much don’t have actors.”

Discovery’s differentiator is that its core channels are built around subjects that have natural and often passionate affinity groups. Viewers of Discovery, Animal Planet, Food Network, Science Channel and such “tune in for a curated brand that gets them.”

The core group of brands among its 19 U.S. outlets are: Discovery Channel, HGTV, Food Network, TLC, Investigation Discovery, OWN: Oprah Winfrey Network, Animal Planet, Motor Trend Network, Travel Channel, Science Channel, and DIY Network.

In making the pitch to advertisers, Discovery ad sales chief Jon Steinlauf noted that the high volume of live viewing on Discovery channels was a better fit for marketers looking for mass exposure. Some 97% of commercial ratings points are generated by live viewing with a preponderance of upscale viewers.

Steinlauf went so far as to say that “most of our shows have ‘shoppable moments’ that ignite consumer activity.”

Coinciding with the upfront, Discovery unveiled a slew of programming news across its key channels. Among the highlights:
