With the current technology that we have today, digital marketing is indeed one of the common avenues to promote basically anything.
The reach is quite fast and the influence is staggering especially if you use popular personalities.
Social media alone will give you the exposure that you want, without even spending any penny.
It depends on how you use these channels to your own advantage.
Digital strategies cannot exist alone. Even marketing experts agree that modern marketing is a merger between the old and the new. That is the tradition and modern(digital) strategies. The old and marketing strategies cannot be thrown away because they are essential in reaching certain demographics like baby boomers who prefer print newspapers. While digital strategies may reach the millennials and genz who prefer online adverts popping up on their screens than reading newspapers.
I guess almost everything we have cannot exist alone no matter how mainstream the new ones are, and this includes old and modern way of advertising your product. So, yeah I agree on this one. However, there might be a changes on production for an old way of advertising such as publishing it into newspapers and magazines or anything like that due to the emergence of the internet. We might see fewer companies that is still interested in continuing such strategy, maybe it purely depends on their target market.
Majority of the young people, maybe below the age of 25-30 years old are not into newspapers, so companies who has a target market at these age brackets may simply use the internet to reach them.
Companies who target an older customers will most certainly continue to use the newspaper advertisement.
Old ways cannot be totally eradicated, especially when it was too successful before the arrival of the modern and mainstream one.
