Evidently no one cared enough to file a petition to deny in order to prevent or delay the transfer from occuring. But that train has left the station.
No point. What would the grounds of petitioning have been? Unless there's a reason someone isn't qualified to be a licensee or a proposed assignee has outstanding issues with the Commission, the FCC isn't going to do anything other than slightly delay a transaction. The FCC hasn't denied a transaction due to a format change or staffing concerns in over 40 years. You're not going to see a denial based on concentration of ownership, like what happened with Standard General and TEGNA earlier this year, over a company that operates a handful of formats and never pushes the outer limits of ownership either.
