Events: distinct conference editions on which the company is listed, ConferenceDB, as of today.
How this was counted
An event is one edition of a conference or trade show (CES 2026 and CES 2027 are two). A company counts at an event when it is listed there as a sponsor, partner, media partner or exhibitor on an edition ConferenceDB publishes. Companies are matched on their website domain, so subsidiaries with their own domain count separately, and marketplace domains that stand for many sellers are left out.
Counts grow every day as lists are added, and past editions are included. They show how many events a company has been seen at in our data, not how many it has attended in total.
