THE "GOLIATH" MEME continues to be spread in the media; that is, that the inscribed postsherd from Tel es-Safi has the name "Goliath" written on it, whereas in fact, at least according to this Jerusalem Post article, there are two names similar but not identical to Goliath: 'WLT and WLT (אולת and ולת). The Independent reprints the AP article that makes the claim about the name Goliath, as do many other newspapers.

In addition, epigrapher Lawrence Mykytiuk is interviewed (apparently in a Purdue University press release) about the potsherd with the correct understanding that the names are similar but not identical to Goliath.

Claims are being made that these names, whether Goliath or something similar, have some bearing on the historicity of the David and Goliath story in 1 Samuel 17. I'm not so sure. It's been a long time since I read about this, but I believe Goliath was a family name used by Jews in the first century BCE, which implies it could have been known and used any time between them and whenever the name originated. I can't find an online discussion that isn't behind a subscription wall, but the main reference seems to be:
