A trend means a direction towards which something is changing or developing. In the world today, almost everything is changing from what it used to be. For instance, when compared to the 1990’s, there is a change in the trend of clothes worn and fashion in general.
Again, the trend in communication technology keeps changing and developing; from the landline telephone to cell phones. In business, changes and development have occurred in processing methods, marketing strategies, and so on.
Following the trend in whatever you do could be good especially when performance or output of that thing is dependent on it. However, it is important to note that any trend that does not benefit you should not be followed irrespective of how good it may sound or look.
