MSN Messenger and Yahoo! share the same protocol (SIMPLE)
MSN Messenger uses MSNP, not SIMPLE. I don't know what Yahoo! uses, but it won't be MSNP. The interop is between the two networks using a mapping between the protocols.

Google uses jabber...
I don't think SIMPLE is a defined protocol, I believe it's more like a protocol design technique (NB: I suck at explaining stuff) which both MSN and Yahoo utilise making it relatively easy for their two specific protocols to translate into one another.
Similarly, Jabber is based on XMPP or vice versa - not sure.
EDIT: Well here's what
Wikipedia had to say:

In computing, SIMPLE (Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions) is an instant messaging (IM) and presence protocol suite based on Session Initiation Protocol (SIP). Like XMPP, and in contrast to the vast majority of IM and presence protocols used by software deployed today, SIMPLE is an open standard.
SIMPLE applies the SIP to the problems of:
- Registering for presence information and receiving notifications when such events occur, for example when a user logs-in or comes back from lunch.
- Managing a session of real-time messages between two or more participants.
As of 2006, SIMPLE was IETF work in progress, taking place in the simple workgroup. Some parts have been standardized, e.g. RFC 3428. Other parts, in particular IM sessions, are still under discussion. However, several implementations are already available, notably including the Microsoft Windows Messenger.
SIMPLE is not the only IM protocol suite being developed within the IETF. XMPP, based on the Jabber technology, is a competitor.
Despite its name, SIMPLE is not simple. It is defined by about 30 documents or more than 1000 pages (7 times more than HTTP 1.1, 15 times more than SMTP and IRC).
