Executive VP Marni Walden admitted Verizon is still “learning” with its Go90 video app, a key part of the US operator’s bold media strategy.

Walden confided some content on the millennial-focused Go90 had worked well, while “other content has not done as well”. The app launched in October last year. She was speaking at the Techcrunch Disrupt conference.

Walden did not reveal any usage figures. There have been reports this year that the app failed to gain much traction.

Content that has drawn viewers included live sport and music, said Walden.

“So I think we are learning. We have learned about the platform as well. We have recently moved that to the AOL techstack and added some additional features. I would tell you I am encouraged by engagement, that we have learned a lot about content and you will see us continue to work that model until we get it right.”

Her cautious comments are similar to those made by Verizon CFO Fran Shammo in April when talking about the video app.

Go90 is a major departure for Verizon and a key part of its media diversification strategy alongside the $4.4 billion acquisition of AOL in 2015 and this year’s $4.8 billion deal for Yahoo, which is set to close in Q1 next year.

Walden was on stage with AOL CEO Tim Armstrong, who was quizzed about how the Yahoo deal was progressing, and in particular whether job cuts were in the pipeline.

Armstrong argued Verizon would not have done the Yahoo deal if it was only about “cost structure,” while admitting synergies existed and commenting “I am sure there will job changes but that’s not what this deal has been about.”
