Channels are the latest feature of WhatsApp, in which only the channel creator (admin) can send messages. An unlimited number of people can follow the channel because channels are public so anyone can find and join the channel without permission from an admin.
Channels keep a history of messages to help followers see previous content they missed before joining. Keep in mind that message history will be stored for only 30 days. Anyone can create their own channel to share updates. Many creative and informational channels share the latest updates and informative articles. Look at the following WhatsApp channel links and join according to your needs.
