The document discusses different digital channels - kiosks, apps, and games - and evaluates them based on criteria like information availability, offer immediacy, necessity of virality, level of trackability, and estimated cost per response. Kiosks have none information availability, are accepted, can provide immediate offers, have low virality and trackability needs, and are estimated to have a high cost per response. Apps similarly can provide immediate offers but may face tolerance issues, have high virality potential but low trackability, and are estimated to have a high cost per response. Games are less immediate, have low virality requirements, low trackability needs, and are estimated to have a mid-to-high cost per response,
