Publishers are looking for better ways to manage advertising inventory across channels

Advertising inventory has become more difficult to manage as publishers and media companies expand into digital formats, connected TV, print, and out-of-home advertising. Each channel introduces different availability requirements, pricing structures, and campaign specifications, making it harder to maintain a consistent view of what can be sold and delivered.

The IAB’s 2025 Outlook Study examines the advertising industry’s expectations around media investment, digital channels, and emerging advertising formats. As media portfolios become more diversified, publishers need systems that can connect inventory information with sales operations and campaign delivery rather than relying on disconnected spreadsheets and individual platform reports.

Poor inventory visibility can lead to overbooking, underutilized advertising space, and missed revenue opportunities. Media organizations therefore need tools that provide accurate availability information, support flexible rate cards, and help sales teams understand which inventory can be offered to advertisers across different channels.
