All of the above can be considered precursors to social media.

1. Bulletin boards on the internet: These were some of the earliest forms of social interaction on the internet, where users could post messages for others to read and respond to.

2. ICQ: This was an early instant messaging program that allowed users to communicate in real time, a feature that is now a staple of social media platforms.

3. Early dating websites: These sites facilitated social interaction between users, much like social media does today.

4. IRC (Internet Relay Chat): This is an application layer protocol that facilitates communication in the form of text, and can be seen as a precursor to the chat features on many social media platforms.

So, all of these can be seen as precursors to what we now know as social media.
