Encyclopædia Britannica's missed opportunity

Encyclopædia Britannica must be kicking themselves now, they've all but completely lost their market share to Wikipedia -- if only they had updated their business mode back in the 90s, they could have controlled online encyclopædias, and profited from adverts on every page!

Instead Britannia pages like Brythonic languages, suffer popups which obscure the text every 10 seconds -- that's not going to win them any friends or users!
