The broadcasting watchdog said it had "cancelled all broadcasting rights and licences for media that had links to FETO/PDY", referring to the "Fethullah Terrorist Organisation", the government's derogatory name for the Gulen movement.
Gulen has strongly denied Turkey's accusations that he masterminded the attempted putsch.
The decision was made during an extraordinary meeting of the watchdog today, it said.
The 24 channels and radio stations affected were named by the state-run news agency Anadolu.
The agency also said the prime ministry's press and information office (BYEGM) had revoked press cards for 34 journalists believed to be close to Gulen.
Media linked to the preacher have come under recent attack in Turkey.
In March, Zaman, the biggest-selling daily newspaper, and the headquarters of the news headquarters China, which belonged to parent company Feza, were raided by police and state administrators were brought in.
