Okay, I gotcha. Even though, I'm not sure you could owe the transformation of journalism to any of those guys: it was a natural progression as news became more saturated and access to news became more constant and universal: especially with multiple channels providing 24/7 coverage of a relatively restrictive subject matter (sports which Americans care about). I assure you that shock jocks and cartoonish media personalities existed prior to ESPN, though.
Also, I think a lot of the channel/industry's most popular guys have refrained from developing catch phrases, so I'm not sure the situation is as dire as you believe.
I'm guessing you watch a lot of Outside the Lines so that you can get your ultra-dry sports journalism?
