this is the reason why Tamil dubbed fare welll in andra n telagu dub movies fail in tamil ................
High publicity cost :
The cost incurred to publicize a big-budget Telugu film is about Rs 75 lakh and can be stretched to about a crore, if the film is a superhit and has a long run in the boxoffice. Where as a Tamil requires Rs 2 crore and upto Rs 2.5 to do an elaborate marketing campaign in TN. Even small budget Tamil films have to shell out such big monies to publicize their film.
One of the reasons for such high costs is – in Telugu, Producer’s Council restricts the number of ads a Producer can put on TV & print. In return it also subsidizes the cost of trailer. It costs Rs 3000 (on the higher side) for a 30 second TV spot in a Telugu channel for a Telugu film, where as the rates for TVCs in Tamil channels go upto Rs 20,000 for a 10 second spot, making it very expensive for Producers to buy TV spots. Unlike in Telugu, Producers do spend a lot on magazines, radio and outdoor since each of those mediums have a huge reach.
Putting it in perspective, a dubbed Tamil film just needs to spend Rs 40-50 lakh to a do a good marketing campaign in AP, where a Telugu dubbed film has to shed nearly Rs 1.5 crore to do the same in TN. This is another barrier to entry. As it is Telugu films are yet to have a market in Tamil & having to spend such huge amounts only on publicity further deters Producers from trying to release Telugu films in TN.
