| How it reaches B2B buyers | CAASieBy screen, place and time: you choose the boards and when your ad plays. | AdBuyMCPEach channel is aimed at your market with the targeting its seller offers: places and times of day for out-of-home, business data such as company size and industry for streaming TV where the seller offers it, shows and categories for podcasts, and the topic of the conversation for ChatGPT ads. None of them targets people by job title in the UK. |

No media has been bought through AdBuyMCP yet, so your campaign would be among the first. |
