Methods, systems, and computer readable media can be operable to facilitate real-time advertisement verification. Advertisement media may be tagged with one or more tag identifiers. One or more remote probes may retrieve tag identifier(s) from advertisement media and output tag information to a centralized verification system. The centralized verification system may compare tag information retrieved from remote probes to expected advertisement placement parameters. The centralized verification system may verify that appropriate advertisement media has been spliced into expected channels or streams. When a splicing error has been detected, the centralized verification system may initiate changes to correct the splicing error.
