If we look back the history of Bangladesh, we see examples of ancient kings and land lords who sponsored cultural activities, making literature, music and art flourish in the region. In the present era, we see affluent corporations, mostly telecom companies in Bangladesh, taking their place.
They have been going the extra mile to sponsor a wide variety of cultural pursuits, including a rural festival celebrating Fakir Lalon Shah  (c. 1774–1890), a popular Bengali baul saint, mystic, songwriter, social reformer and thinker, but not always with positive reception.
Zahid Islam  at the blog Alal O Dulal explains how corporations are selling the Lalon culture:
In 2007 for the first time in history, Lalon Phokir’s Dol Uthshob (Lalon's Dol Festival) was held under sponsorship, with promotion campaigns so aggressive and ill designed it disgusts me to even remember it. Since then Grameenphone and Banglalink (telecom brands) took turns in sponsoring the festivals.
He also mentions that Lalon festival is getting a modern shape under corporate banner:
The first time around, those of us who had been visiting Cheuria for many years, were shocked to find the sponsorship junks.
And the need to protect their sanctity:
There are many people and organisations, home and abroad, that feel we need to “protect” the baul  way of life. I do not necessarily agree with this notion. Rather I feel our intervention is what creates most of the “problems.”
