Will MTV ever go back to actually playing music/videos?
Actually, yes, but not in the way we remember music videos being played in the 80s:

Good to see they're getting back to their roots, slowly. And MTV News and Unplugged would be good for the channel to invest in again.

As for the topic of the thread, the only bubble that burst is that of the author's own premise for the article. Yes, there's a downturn, but the top teams, conferences, and sports will still get top dollar--the only difference is that the industry is being more discretionary about their spending, both in the length of contracts *AND* what they pay for.
Frankly, the B1G's deal for $250m/year/six years for HALF of the ESPN inventory currently shows that there is no bubble, per se. Just ESPN overestimating their ROI on named talent and some of their questionable acquisitions (e.g. Longwhorn Network) and paying the price for it. Hell, if the rate holds up for the other half of ESPN's B1G Tier 1 inventory, the B1G will make in six years that the SEC will garner in 15 (~$3b/15year deal from 2013). That's a hell of a disparity in our favor compared to the SEC schools, and everyone else in college football for that matter.
And thanks to the FCC wisely choosing to regulate ISPs as utility providers, we're going to see traditional television providers (e.g. Comcast, Verizon, Frontier) be marginalized in favor of multiple ISP-delivered television subscription choices, like DirecTV's offering, Sling TV, or Sony's Vue. All of those TV-over-IP subscription offerings have competitive rates and as close to a la carte programming as we can get currently.
