As you keep scoring success your image builds as a celebrity and it also increases your brand value. This comes beneficial when you have to make an endorsement, a live show appearance or a stage show. This is more applicable for the music directors and singers.
Having said that, at a regional level our folks may be considered as super hot celebrities but they cannot shine in international circuits. If they have that international glamour and recognition like Britney spears or Justin Bieber only then it works.
There are many Tollywood celebrities who tend to fizzle out at international level. Secondly, the Telugu NRIs also get appealed only when the prices are reasonable. Just because the star value holds strong in the local level, the same doesn’t work outside. Hope the observation gets noted.
