May be i am wrong but let me quote a passage from dawn for your clarification.

SHANGLA: Divisional president of Pakistan Peoples Party Afsarul Mulk said on Sunday that the Pakistan Tehreek-i-Insaf-led government had failed to deliver during last four years in Khyber Pakhtunkhwa despite its tall claim of change.
As per the highlighted line the PTI govt had failed to deliver. Likewise, we can write Media has failed to deliver not has been. You can check further through google.
