English to Arabic Social Sciences Media / Multimedia

It is defined as: Beat reporting is the craft of reporting on an issue or particular sector, organization or institution over time. Beat reporters build up a base of knowledge on and gain familiarity with the sector, allowing them to provide insight and commentary in addition to reporting straight facts. This distinguishes them from other journalists who might cover similar stories from time to time.

Can anybody provide me with an Arabic term that can do the job?

Thanks in advance
