Looking for a chip to connect to internet and display text
I am not sure if there is a single chip avaialbe to do this, but you can have a look a few examples.. 

The arduino can be be programmed very easily and all the tools, code and IDE is free and open source. This not the only available one and there are several different architectures that benefit from their own subset of features,pros and cons. Building a simple internet bassed arduino wont cost you too much. But this is not recommended if you want to go mass production though.

Here are some projects that could interest you.
