# Promotional digital signage and offer screens Running promotional and offer content on screens with date-scoped scheduling, so a campaign appears on its start date and stops on its end date across every screen on the channel. Source: https://channelos.tv/use-cases/promotions-and-offers ## What runs it ChannelOS plays as a web page in the browser the screen already has: Android TV, Google TV, webOS, Fire TV, a Chromebox, or a laptop in kiosk mode on the HDMI port. There is also a native Android TV app, downloaded as an APK from channelos.tv rather than from Google Play. There is no media player box to buy and no per-device licence. ## What goes on the screen - **A campaign placed on its dates.** The offer board occupies the days the offer runs and the ordinary board resumes on its own afterwards. Expiry is scheduling, not a reminder. - **Up everywhere on the day.** Screens tune into a channel, so a campaign goes live across every site at once rather than being loaded screen by screen. - **Proof it actually went up.** The screens board shows what each screen is playing right now, which is the real question when somebody asks whether the promo landed. - **A different offer by time of day.** A quiet-hour offer on the afternoon hours and the full-price board the rest of the time, both on one channel following its own clock. ## When ChannelOS is the wrong answer ChannelOS has no pricing or promotions engine. It does not read a price file, does not integrate with a POS or an ERP, and does not know what an item costs, so a figure on a promo board is typed and a price changed in your systems will not change on the screen. There is no approval workflow either, so if customer-facing offer copy needs sign-off, that happens outside ChannelOS. There is no audience measurement, no proof-of-play reporting for an advertiser and no footfall attribution, so if you are selling promotional slots to third parties and have to report plays, buy a product with proof-of-play. ChannelOS fits your own promotions on your own screens. ## Questions ### How do I make an offer stop showing when it expires? Place the offer board on a channel timeline with an end date. A channel is a named feed with a real daily, weekly and date-scoped schedule, so a campaign running to the thirty-first occupies exactly those dates and the ordinary board resumes on the first by itself. Nobody has to remember to remove it, which is the failure printed promotions have. ### Can one promotion go live across every site at once? Yes. Screens tune into a channel rather than being updated individually, and what a screen shows is derived from the schedule in real time, so editing or scheduling the campaign reaches every screen on that channel within seconds. The screens board then shows what each one is actually playing, which is how you check rather than assume. ### Can I run a different offer at different times of day? Yes. Boards sit on the hours you place them on, so a quiet-afternoon offer can hold the afternoon while the ordinary board takes the rest of the day, and the weekend plan can differ from the weekday one. Once set, it runs whether or not anybody is on site. ### Does it get prices from our POS or price file? No. There is no POS, ERP or price-file integration of any kind, so what is on the board is what someone typed. If promotional pricing has to be driven from your systems, a retail signage product with that integration is the right purchase. ### Can I report plays to an advertiser who paid for a slot? No. There is no proof-of-play reporting, no audience measurement and no impression counting, so ChannelOS cannot evidence that a third party's ad ran a given number of times. Selling slots to advertisers needs a product built for that. For your own promotions on your own screens it is not a limitation most people notice. ### What does it cost to run promotions on several screens? Per screen per month at the rates on the pricing page, with the first screen free forever. Free screens carry a ChannelOS banner that opens into a full slide roughly every two minutes, which on a customer-facing promotional screen is normally a reason to be on a paid plan. ## Related - [Digital signage for retail](https://channelos.tv/digital-signage-for-retail): Promo screens on displays you already have, and the campaign that ends itself. - [Car dealerships](https://channelos.tv/industries/car-dealerships): Monthly finance offers that come down on their own. - [Many screens, one channel](https://channelos.tv/blog/manage-many-screens-with-channels): Why the tenth site is the same work as the second. - [Pricing](https://channelos.tv/pricing): What a paid screen costs, and exactly what the free screen includes.
