Jennifer Maas TV Business Writer The new regime at Peacock has spent the past nine months preparing to take its baby bird to new heights. The number of big moves made by the NBCUniversal-owned streamer — from amping up its original content slate to livestream deals with Hallmark, Reelz and Big 10 college football to bringing NBC shows back into the fold for next-day viewing and eliminating its free tier for new users — is setting the stage for what executives hope will be a growth spurt in 2023. Peacock, which launched three years ago last month, will show of its brighter plumage Tuesday with its New Fronts presentation to advertisers. “It’s all coming together,” says Peacock president Kelly Campbell, who signed on in October 2021 after serving as president of Hulu. “We’re just seeing an increasing interest overall when it comes to inflow and engagement, and people are stickier than they were in the past.”
