BBC Scotland Director Donalda MacKinnon predicted the new television channel would be a success over time.
She told BBC Radio Scotland: "I'm certainly not fixated on a particular audience segment at this stage.
"I think it would be folly to try too hard to anticipate numbers - either low or high.
"What we're looking to achieve is success over time and I guess audience appreciation in Scotland."
What was there to see on launch night?
The first programme - a special one-off entertainment show - was presented by Iain Stirling, the Scottish comedian best known for his Love Island voiceover.
"A Night At The Theatre" featured chart stars Lewis Capaldi and Nina Nesbitt, as well as comedians Elaine C Smith and Larry Dean.
