This is a technology truism: "New technology breeds more new technology." Let's take the explosion of mobile data. Smartphones and iPhones are creating a huge traffic jam in wireless communication. At present we are using fixed cell towers to transmit data from towers to the Internet.

The need to handle the mobile explosion is putting extreme pressure on present tower operators to upgrade their equipment or build new towers. This is a cumbersome, time consuming process.

Comcast Corporation (CMCSA) reported earnings for the fourth quarter on Wednesday. Today, the company's shares hit a new 52-week high of $25.39 during the intraday session (there's still more than two hours left until the closing bell rings, so that high point could eventually change).

The 52-week low for the cable business is $15.55. The one-year chart tracks the positive momentum of the equity. Will the stock break out to new heights from this juncture?

The recession is taking its toll on TV cable providers. High unemployment and low wages are the main causes for the drop off in viewer numbers. Craig Moffett, analyst with Sanford C. Bernstein estimates that cable and satellite companies lost about 330,000 customers in the third quarter, as reported in the New York Times.

Customers are cutting cable service and returning to the old 'rabbit ears." Antennas Direct, maker of the new style rabbit ears expects to sell 500,000 this year, up from 385,000 in 2009.The cost is is between $25 and $150.

I am maintaining a buy recommendation on Shaw Communications (SJR) despite an underwhelming year-end financial report.

I originally recommended Shaw in my Internet Wealth Builder newsletter on Feb. 4, 2008 at $20.64. Calgary, Alberta-based Shaw, is a telecommunications company, which dominates the rich Alberta market. It recently also purchased the bankrupt CanWest Global television empire. Shaw is a low-risk company that won't suddenly shoot up in price but that compensates with limited downside, steady cash flow, and long-term growth potential.

A bright and shiny conference call has today boosted shares of Time Warner Cable (TWC). The stock has risen in the range of 5%, with shares trading at a healthy $62.34 as of this writing. The company reported a 5.7 percent increase in third-quarter adjusted operating income before depreciation and amortization, via its 8:30 am conference call today. However, investors might wish to think carefully before loading up on too many shares of this stock.

At least initially, investors liked what they saw in Comcast Corporation's (CMCSA) first quarter report, during which the company earned 31 cents, above the Thomson/Reuters First Call first quarter EPS estimate of 30 cents. Shares rose
30 cents to $18.76 in Wednesday afternoon trading, despite a choppy market.

Comcast, the nation's largest cable television operator, said it added 399,000 high-speed Internet subscribers and 373,000 phone customers in the first quarter. Comcast lost 82,000 basic video subscribers, but average revenue per video subscriber increased 6.3% to $122.98 per month. The company earned 27 cents per share a year ago, in the first quarter of 2009.

Cablevision Systems Corporation (CVC), post-spin off of Madison Square Garden (MSG), has understandably dipped, but the latter has been more than offset by MSG's current share price, about $19, as Cablevision subscribers were allocated one share of MSG for every four shares of CVC.

I'll review MSG's business model in the weeks ahead. For now, I still like Cablevision, first written about on May 29, 2009, at a price of $19.03.

Comcast (CMCSA) published fourth-quarter numbers earlier today. On a reported basis, net income more than doubled to 33 cents per share. According to Reuters, the cable company earned 29 cents per share on an adjusted basis, beating estimates by two pennies.

Management loves to promote its ability to generate free cash flow. There was an increase in this metric of just under 21% for the twelve-month period. I love free-cash generation, and I appreciate this example of growth, but one thing should be pointed out: operational cash flow was flat. As the earnings release stated, a reduction in capital expenditures was mostly responsible for the expansion. Free cash flow was down 11% for the fourth quarter itself, sorry to say.

Cable giant Comcast (NASDAQ: CMCSA) posted Q3 numbers earlier today. It seems like the company is doing well with earnings growth and cash flow, even if revenues moved up a meager 3%.

Adjusted earnings per share grew over 20% to 28 cents per share. According to our earnings preview, the market was looking for 25 cents per share. Operating cash flow increased a little under 3%, but free cash flow went up almost 20%, aided by a smaller amount of capital expenditures compared to the previous year's similar quarter. I'm sure shareholders are more than satisfied with the growth rate of the green stuff over the past three months. Comcast saw excellent expansion of free cash over the last nine months, too.

It looks like Cablevision Systems Corporation (NYSE: CVC) is starting to get-it-in-gear. Hence, I'm reiterating my Buy rating for CVC, first recommended on May 29, 2009 at a price of $19.03. If you purchased CVC then, you're up about 30%.

Even ignoring the potential spin-off of sports arena Madison Square Garden, Cablevision's positives have always been compelling: fifth-largest cable t.v. operator (about 10.4 million revenue generating units), with a strong presence in a lucrative market (New York City area, 3.1 cable t.v. subscribers); included in that are about 2.8 million premium cable t.v. subscribers, called iO Digital; nearly 2.5 million high-speed internet subscribers; and 1.9 million internet voice (telephone) subscribers.

There's some exciting news in the world of World Wrestling Entertainment (NYSE: WWE). Looks like Vince McMahon wants to expand his media empire via entering the world of basic cable. Yes, he's already on basic cable, of course, but now he's intent on literally creating his very own wrestling channel.

According to a blog at the Los Angeles Times website, McMahon would be interested in launching a dedicated WWE channel within two years. This makes complete sense on several levels. First, WWE has a lot of content in its library that needs to be monetized; WWE's existing video-on-demand product already leverages the company's portfolio, but exposure to ad-supported cable would be helpful. Second, it could boost the profile of the WWE brand. Third, it might help long-term growth; without question, WWE needs to do something to compensate for the falloff it is seen in pay-per-view buys.

It's a close call, but I'm Reiterating my Buy rating for Comcast Corp. (NASDAQ: CMCSA), first recommended on April 22, 2009 at a price of $14.05.

Comcast's stock has moved sideways, basically, for the last six months, so a caution flag nevertheless has been raised. The stock has straddled the 50-day moving average during that period, suggesting that institutional investors are concerned about Comcast.

Comcast (NASDAQ: CMCSA), the high-profile cable and Internet provider, produced some good second-quarter stats on Thursday. Reuters says that the 33 cents per share earned in the period beat estimates by 7 cents. According to the company press release, sales increased over 4% and operating cash flow expanded by over 5%. Free cash flow, however, was flat in Q2.

That wasn't a big deal, though. The free cash covered both the dividend and the monies used to repurchase shares. In fact, Reuters reported that the buyback activity in the quarter represented a resumption of the program. We can take that as a positive sign of confidence from management.

Right now, over at Hulu.com -- a joint project of News Corp. (NYSE: NWS) and General Electric Company's (NYSE: GE) NBC Universal, viewers can check out recent editions of, for example, The Daily Show or Man Caves, among many other programs normally viewed on cable networks such as Comedy Central or the DIY Network. Viewers need a computer and a high-speed Internet connection to catch these programs, but they don't need a cable subscription (or even a television!).

Comcast Corporation (NASDAQ: CMCSA), a cable/broadband entity that competes with Verizon Communications Inc. (NYSE: VZ) and DISH Network (NASDAQ: DISH), reported earnings for the fourth quarter on Wednesday. Adjusted revenues increased 7%, and earnings per share jumped 35% to $0.27. Not a bad performance, and in fact, earnings beat estimates by four pennies according to this source.

Perhaps the biggest piece of news in the release is the increase in free cash flow for the full fiscal year. That jumped 56% to $3.7 billion, driven in part by a decrease in capital spending. I liked reading that management intends on focusing on free cash flow. It better, because it's going to be a challenging environment for the cable business, and the company committed itself to raising its dividend by 8%. On the flip side, though, as has been noted in a couple news reports, Comcast stated in the release that it doesn't feel like buying back stock at the moment. That won't be comforting to shareholders who have seen their shares hovering closer to a 52-week low than a 52-week high.
