Nah, Comcast wasn't shedding any tears after announcing its Q1 2008 earnings, but DirecTV must be grinning from ear-to-ear. Aside from seeing its earnings rise 10-percent and revenues climb 17-percent, the satcaster also managed to grab 275,000 net subscriber additions. Analysts were quite pleased with the exceptionally low churn rate, as many of its subscribers seem to be staying put. And with close to a hundred HD channels on tap, who can blame them? It was also noted that average revenue per subscriber crept up from $73.40 to $79.70, and an increasing demand for high-definition programming and DVRs were largely to thank. Is making the switch from cable to satellite worth it? Seems that quite a few folks said yes with their wallets this past quarter.
