Public relations (PR), what it is and how it relates to marketing
Public relations (PR), known in Czech rather impersonally as vztahy s veřejností, plays a key role in shaping how the general public perceives companies and individuals. As a field, PR is essentially the strategic management of how information about an...

My 2024

What caught my attention at Brand Restart 2024
