It's one of the most famous businesses from the dot-com revolution and with 175 million active registered users, eBay is still wheeling and dealing strongly in 2018.

But what was the first thing to kick it all off?

Well, back in 1995, computer programmer Pierre Omidyar wrote the code for what he called an "experiment." He wanted to know what would happen if everyone in the world had access to a single global marketplace.

To test his idea, he came up with an auction website (originally called AuctionWeb), where he listed a broken laser pointer that he was going to throw away. In the end, a collector bought it for $14.83.

Dave's World also explains what the word 'tsundoku' means. It's something a lot of people are guilty of - here's a clue: from the Japanese "tsumu" - to pile up- and doku- to read, reading.

And the Dermot and Dave team even had time chat about their mum's rad communication skills! I think Dave should call his mother the 'Meme Queen'.
