Thinking about it - was it really a good idea for WWE to embed the links inside the Twitter thing for many weeks on RAW? Let's take a look at the YouTube hit count for each of the videos - this is normally reliable, so no reason why it wouldn't be here:
<-- 443,186 views (November 21st - ItBegins2012)
<-- 258,083 views (November 28th - second2012)
<-- 159,956 views (December 5th - lookwithin2012)
<-- 121,417 views (December 12th - 2012control)
<-- 207,743 views (December 19th - prophetless2012)
The very first, direct, video has 443k views - to put it another way, that's 10% of RAW's audience
. The December 12th video only has 121k, that's 3% of RAW's audience
. Can you create a buzz from 3 percent of your audience?
Also, outside of wrestling circles, Chris Jericho is not a 'buzz' figure. Okay, he has his music career, but Fozzy is not a big band by any stretch of the imagination outside of wrestling and was not a main figure during the Attitude Era, more of a mid-carder (although this is probably a controversial statement).
EDIT - thanks Brye, have edited my opening post slightly so it's clearer for future weeks.
