For as long as we can remember, there's at least two major telecom rumors that never seem to die -- yet never seem to occur. One is AT&T's supposed interest in acquiring either DirecTV or Dish Network. The other is the idea that the Dolan family is looking to offload Cablevision, the most likely suitors being Time Warner Cable or Comcast. That latter rumor resurfaced this week, with Boyar Asset Management boss Mark Boyar (who?) telling Barrons that "I think the Dolan's have positioned the company for a sale." There's not much evidence to support that a sale will happen, just some griping about the fact that Cablevision's earnings were a bit off last quarter, largely thanks to the fact that Cablevision enjoys fairly heavy penetration in existing markets.
