It's a good question.
Do you keep on hosting or attending a certain standing meeting that is no longer useful? It's 2018; time to rethink your options.
Start with clarifying the objective by asking, what is the purpose of the meeting?
If it's to share an update - consider updating via email, google doc, or dropbox paper.
If it's to brainstorm - share that goal so that everyone comes prepared to be creative.
If it's to collaborate - send out some reading or data in advance so everyone can show up informed and ready to share.
Ask yourself what needs to happen in the meeting and then prepare accordingly before the meeting.
