Today marks 30 years since the premiere of ESPN. Happy birthday, ESPN! Hard to believe there was actually a time when there wasn't a cable channel devoted completely to sports. In fact, the idea of a cable network that just covered sports was considered as ridiculous as one that only reported the news. Don't even get me started on the radical notion of an all-food channel or one that specialized in weather!

Yes, once upon a time, all those concepts were deemed losers. Back in 1979, if you wanted to know the score of a game in progress, you had to hope it was playing on the radio or TV to tune in. Or, more often than not, wait till the local news broadcast at six o'clock for the score. How did we ever get by?
