A more thorough explanation:

Definition: Dissemination (di-sem-i-nay-shən) is the act of spreading, diffusing, or dispersing something. This can include ideas, information, or even rumors.

Examples:

• The dissemination of information about the dangers of smoking has led to a decrease in the number of smokers.
• The dissemination of fake news on social media can have a negative impact on people's beliefs and actions.
• The dissemination of a new product through advertising can increase its popularity and sales.

The examples illustrate how dissemination involves spreading something to a wider audience. In the first example, information about the dangers of smoking is being spread to encourage people to quit. In the second example, false information is being spread, which can have harmful consequences. In the third example, a product is being promoted to increase its reach and popularity.
