Following these each process gives sustainable market for marketer [1]. of active mobile phone connections. Since 2000, there has been exponential growth in the number of cell phone users in India (see Figures 1 and 2) [5].
It is also estimated that by 2019, there will be about 299 million smartphones in India as compared to 140 million in 2014. Low cost smart phones running on low cost operating system like Android One are fuelling the rise of smartphones in India. It is also estimated that there will be 527 million total Internet users in 2018, up from  213 million in 2013. Thereby given their reach, the combination of mobile and internet technologies has the potential of engaging a billion people in India [5] (Figures 3 and 4).

Change in consumer behaviour
Today's consumer is tech savvy, socially empowered, information rich and lacking time. At the same time, technology is quickly evolving and embracing the needs resulted from new consumer motivations. Consumers' ability to influence fellow consumers and companies alike is much bigger than earlier generations [2].
As a result, consumers expect the world at their fingertips, when they want it, how they want it and where they want it. Shopping is not a planned destination or  event-they are shopping, 24/7. And they want an authentic shopping experience tailor-made specifically for them.
'Generation Z', want it all. They want to make an impact to the world and share all of their experiences on their journey. They strive to be authentic, socially sensible and in many cases value purpose over cost. They are driven by ambition and a strong moral conscience. They strive to independency, are more vocal and more informed than any generation before them. They are cognizant, engaged and choosy. They expect these standards are met by the businesses with which they deal with or take their business elsewhere. Furthermore, they will express their opinion, available for other fellow consumers to read.
With the onset of 1990s, Indian politics has seen digital changes where computerization and digitalisation invited by political leaders. Telecom revolution and IT revolution was started by the then prime minister of India Late Mr Rajiv Gandhi, which paved the way for many global players to enter the Indian economy. These companies saw India as a big opportunity and rushed to cater to middle class consumers-an estimated people of 200 million. India became biggest consumer of world for most industry section and responded to world market at double pace to see economy boosting. This elevated again with the launch of mobile at cheapest rate bringing mobile revolution in 2000 and Internet revolution by Jio in 2017 in India. These two steps paved India to see the world in similar specs as developed countries are seen bringing global market on tips. India with its strong growing GDP around 8% bring sustained market place for big MNCs, Although, current GDP rate reduced to 6.6% due to several recent government policies like demonetisation and GST implementation, country is focussed to see $5 trillion economy which is boosting global MNCs to cater Indian market. Beside economy, India stood first with highest youth population of world making country biggest market place and prominence to accept digital market [6].

These materialistic characters bring nation close to keep youth busy and demand for easy and fast life. Digital sense became key and focussed on requirement by mass [7].

Consumerism is becoming a way of life in India
A study on Indians' savings goals reveals the increase in materialism. Savings and property making for next generation is long term priority, life's pleasure and status symbolism have gained importance in last decades keeping growth in tendency for Indians money aside for electronics and smart gadgets (Figures 5 and 6).
Digital marketing accounts a new way to promote products thereby wholesale and retail industry are largely affected with its implementation. Reference to ICRIER (Indian Council for Research and International Economic Relations), retail market accounts to 10% of India's GDP. It is sparked with increasing footfall of customer base, rising Indian economy, fast face life of youth, adoption of change in lifestyles and growing concept of Make in India. Organised retail sector is likely to have growth rate near to 45-50% p.a. and booming further with adoption of digital technology.

This sector is considered unorganised and tapped with many intermediaries due to which farmers has to sacrifice profits, this leads to necessitate removing middle men thereby bringing concept of Farm to Consumer (F2C). Agriculture has seen phases of changes as shown (Figures 10 and 11).  Many companies are now working to bring realisation of precision farming which would be catalyst in meeting food requirement of future. Current agricultural requirement be it F2C or precision farming necessitates integration of digital marketing in agriculture.
Precision farming is true data driven concept for managing resources and optimising crop production. In last few years, industry has seen agriculture machines are getting equipped with smart intelligent devices to monitor, capture and bring analytical view while working in field. Agricultural machinery giants like New Holland, Case, John Deere, M&M adopting digital technologies like Sky watch, Eagle Eye, Digi Sense to ensure enabling steps in precision farming. Few digital apps like Mach Rent, CapTon, Farm Passion, DeHaat, Big Basket, Grofers, etc. are connecting farmers with consumer.

This shows the trend in agriculture integrating digital mechanism into farming practises.
These practises are focussed to increase average crop yield and increasing farm efficiency. One research of Goldman Sachs says there is potential of 1969 US$ bn global crop value by 2050 showing increase of 70% over current value [10] (Figures 12 and 13).  The value of digitalisation in precision farming aims to bring better profit and easiness which is targeted to bring educated youth in this segment.

The challenges evolve every year with the technological advancement in digital platform. Risk of yesterday is gone, and unseen factors of tomorrow are the threat to digital platform. Competition to be as top brand is perceived as biggest challenge in digital world as brands must evolve themselves to understand the evolving need of consumers.
