why asianet movies and surya movies are not doing any padmarajan/bharathan movie festivals ???

even in the birthday week of mohanlal/mammutty they are doing movie festivals. I have a feeling like old gold directors are being forgotten, and i have noticed they are not putting any of these directors movie in the so called channels. Atleast they can do a tribute for directors like padmarajan/bharathan/KG George/Lohithadas what is your thought on this??????
