Q.7 Case study
Solve the questions that follow the case study :
In 1990, two Government decision seemed to sound the death knell for one of the most amazing growth stories of the '80s: the pan masala and chewing tobacco market. First, the printing of a statutory health warning and then the advertising on Doordarshan was banned for the category.
The market grew from around Rs. 10 crores in 1977 to at lest Rs. 250 crores by 1990. The growth had been most explosive after the launch of Doordarshan National.
The principal consumer segment is the North Indian middle class, which forms the largest chunk of the National Network audience.The industry estimates the market to be growing 10-15 percent per annum.
The ad ban does not extend to cable. The market-research agency Admar estimated that Cable TV had a reach of 79.9 lakh viewers and the maximum viewership was a high as 68 percent compared to Doordarshan`s maximum viewership of 70 percent at that time. Cable advertising concessionaire for 80 percent of the films generated by Hindi film industry.
Films stars have a mass appeal and attention grabbing value sachet packaging has created a market among the most unlikely segment, young people. The very segment that had considered pan masala unhygienic has now become loyalists to the new product.
"Our product is targetted towards those who had luxurious lifestyle and treat Bata Zarda as a luxory item". Says the CEO Bata Zarda. Except for Bata Zarda, most gutakas and pan masalas suit middle class pockets and some fo them cost as low as Re. 1=00 per sachet.
The impact of Pan Parag`s advertising during 1986-87 can be felt even to day.
The bottom line seems to be that as long as ethnic is in, and cegarette smoking considered injurious to health, pan masala will not have a falling market.
(a) What strength do you identify in the marketing plan of the product that even after being banned for advertising on the National Network the industry is growing.
(b) Suggested a research design to find out the market opportunities.
(c) Suggested a new product in the same product line to be launched in next one year along with a complete marketing plan.
