Finding out which cartoon character you were could take up an entire evening.A two-minute trailer could take far longer than two minutes to buffer.Message boards were packed with secret codes to unlock levels and characters.Changing your whole computer to look like your favorite movie was a big upgrade.Players spent hours leveling up characters in huge fantasy worlds right in their browsers.You could pick a room about almost anything and start talking to strangers.Watching an auction’s final seconds tick down was surprisingly intense.Fans kept their favorite stories going long after the books and shows ended.Online chess, checkers and card games connected players from all over the world.A dancing animated card in someone’s inbox was the sweetest way to say happy birthday.
