Wikipedia:Articles for deletion/2009–10 Greek television schedule
Similar efforts to delete historic US television schedules  in the basis of  have failed, since that guideline says "historically significant program lists and schedules may be acceptable." TV Guide helps you choose what to watch out of the programs which are going to be available to watch, now or in the future. No one is going to try and use a 2010 schedule to try to decide what to watch. I do not have the ability to read Greek writings about television programming decisions, but in the US case there is quite a bit of reliable sourcing with discussion of how scheduling decisions aided or hurt viewership of programs. Having  block of comedy or drama on a given evening helped create "must see TV" in the era before Netflix binge watching and digital VCRs.  Putting a popular program up against  some ultra-popular show might be its death knell.The history of what programs were broadcast on what nights, at what time, against what competition, is a notable part of modern culture
