The three types of meetings are closely related but differ in both the degree of focus on a specific theme or topic and the limitation to a specific membership of an organization.

Association Meeting:

Definition: This is typically a gathering of members belonging to a specific association or professional group, focusing primarily on internal matters such as member updates, elections of leaders, or discussions on organizational governance.

Audience: The attendees are usually members of the association, and the content is tailored specifically to their interests or professional development.

Example: An annual meeting of the American Medical Association where members gather to vote on association rules and discuss developments in the medical field.

Convention:

Definition: A convention is larger in scale and involves participants gathering to engage around shared interests, usually within a specific industry or hobby. Conventions often include a mix of sessions, panels, and exhibitions.

Audience: It attracts a broader audience which can include professionals, exhibitors, and enthusiasts. It is not limited to members of an organization.

Example: Comic-Con International, where fans, artists, and professionals from the entertainment industry come together to celebrate pop culture, participate in panels, and preview upcoming releases.

Conference:

Definition: A conference is a formal meeting for discussion, typically centered around a specific theme or academic field, and is more formal than a convention. Conferences often feature keynote speakers, panel discussions, and workshops.

Audience: This is usually attended by professionals and experts looking to network, share research, or discuss advances in a particular field.

Example: The TED Conference, where thought leaders and experts present talks on various issues ranging from science to business to global issues.
