Research on Digital-out-of-home Signage

My supervisor gave me four more companies that provides digital-out-of-home signage network and asked me to do research on them. I looked through their websites and tried to find out information on their products and services, network coverage and service rates. So far, I have done researches on eleven companies, which all provides the digital-out-of-home signage networks, but slightly different in their services and products. I think the best company among these is the one allows its clients to view pricing rates, locations, product descriptions, pictures and company contact information. Through the company’s online marketplace, media providers create media profiles for their properties. In turn, advertisers and agencies can use the database of media properties to find the out-of-home campaign. The database has planning information from over 475 out-of-home media sellers.
