PR departments and PR agencies are interested in receiving monitoring of local press on the day of publication, as this is crucial for their effective functioning. This inspired IMM to develop its local branches in most important Polish cities.Thanks to the local branches, it is possible to gather information from most popular local newspapers on the day of publication until 11 a.m. each day.
