Market

Thums Up enjoyed a near monopoly with a much stronger market share often overshadowing its other rivals like Campa cola, Double seven and Dukes, but there were many small regional players who had their own market. It even withstood liquor giant United Breweries Group (makers of Kingfisher Beer) Mcdowell's Crush, which was another Cola drink, and Double Cola.

It was one of the major advertisers throughout the 1980s. In the mid-80’s it had a brief threat from a newcomer Double Cola which suddenly disappeared within a few years.

In 1990, when the Indian government opened the market to multinationals, Pepsi was the first to come in. Thums Up went up against the international giant for an intense onslaught with neither side giving any quarter. With Pepsi roping in major Indian movie stars like Juhi Chawla, to thwart the Indian brand, Thums Up increased its spending on Cricket sponsorship. Then the capacity went from 250ml to 300ml, aptly named MahaCola. This nickname gained popularity in smaller towns where people would ask for "Maha Cola" instead of Thums Up. The consumers were divided where some felt Pepsi’s mild taste was rather bland.

In 1993 Coca-Cola re-entered India after a prolonged absence from 1977 to 1993. But Coca-Cola’s entry made things even more complicated and the fight became a three-way battle. That same year, in a move that baffled many, Parle sold out to Coke for a meagre US$ 60 million (considering the market share it had). Some assumed Parle had lost the appetite for a fight against the two largest cola brands; others surmised that the international brands seemingly endless cash reserves psyched-out Parle. Either way, it was now Coca-Cola’s, and Coke has a habit of killing brands in its portfolio that might overshadow it. Coca-Cola soon introduced its cola in cans which was all the rage in India, with Thums Up introduced alongside, albeit in minuscule numbers. Later Coca-Cola started pulling out the Thums Up brand which at that time still had more than 30% market share.
