Thank you very much Sumner. Good afternoon everybody. Thanks for joining us today to discuss our 2008 fourth quarter and full year results. By now you have listened to enough of these calls to know that I am going to tell you we are operating in a very difficult environment. Some say the worst since the 1930’s. Clearly the market place has been sharply affected by the recession as well as the very unstable credit markets particularly in the last quarter of the year. Our advertising business has obviously been caught in this downturn especially our local businesses having a significant impact on our television and radio stations as well as outdoor. Network and interactive revenue are holding up better and our ratings and internet traffic success are bringing in rate increases even in this economy albeit not nearly at the levels we would like. As you know many of our businesses are dependent on advertising but it is also important to point out that advertising now accounts for just 2/3 of CBS’ revenue. We like the advertising business over the long term. We love its margins. Right now we also like the way our non-ad supported businesses are providing a buffer in this market place. Like most companies today we are primarily focused on managing our businesses so we can capitalize on the upturn when it occurs. We feel the majority of the top line pressure we are experiencing is related to the economic environment and not secular issues. Given the success of our content led by the number one television network we are confident that our results will improve when the overall economy is strong again. Now, over the past year we have taken a number of steps to position ourselves for future success. First, we continue to deliver on our long-term strategy to produce the best content out there. Regardless of the environment creating premium content is at the core of what we do. Second, we took our interactive business to a whole new level with the CNET acquisition. We are in the very early stages of what we will ultimately be able to do with this business but CBS’ record fourth quarter revenue and profits provide a nice preview of what is to come. Once again, for the future we are a content company and the internet is the newest forum for content. Third, to get ahead of the negative trends we knew were coming we acted early to radically lower our cost structure throughout 2008, reducing staff in every one of our businesses and reducing expenses across the organization. As a result, all of our businesses had underlying profitability on an operating basis in 2008 even those most pressured by the economy. Finally, we continue to aggressively manage our balance sheet. Our businesses still generate healthy cash in good times and bad. Nearly $1.7 billion of free cash flow in 2008 and we have used that cash judiciously always with an eye towards meeting our financial obligations, protecting our investment grade credit rating and of course returning value to our shareholders. Given the current uncertainty in the market place, however, we think it is time to retain more of our cash until we have more visibility into the credit markets and the depth and breadth of this recession. As you saw in our release today we reduced our quarterly dividend to $0.05 per share effective as of our April dividend payment. At this level, CBS’ yield will continue to be at the forefront of the media industry. Fred will take you through the specifics in more detail but I would like to stress we are taking this action now because we feel it is wise and prudent. We have until mid-2010 before we have any significant debt that matures and expect to be able to self-fund upcoming maturities through cash flow generated by our businesses. This step will maximize our financial flexibility in meeting our debt obligations. When the economy and credit markets improve we will revisit the amount of our dividend at that time. As I mentioned at the outset the effects of the slowdown were most evident in the last quarter of 2008. Our fourth quarter revenues of $3.53 billion were down from $3.76 billion last year and our adjusted OIBITDA of $591 million in the fourth quarter 2008 was down from nearly $850 million in the same quarter of the previous year. Now let’s take a brief look at some of our businesses. In television the CBS television network is dominating the season. We are up in every single key demographic including viewers, households 18-49 and 25-54. No other network is up in any of these categories. We are also first in viewers, households 25-54 and a close second in 18-49. We are number one in four nights of the week and we have four of the top ten and eleven of the top 20 programs, more than any other network. We are number one by almost 3 million viewers per night. We have the number one scripted series, the number one drama, the number one comedy and the number one news magazine. We continue to cultivate new hits. We have the number one new program in drama with The Mentalist and four of five shows we introduced this year are still on our schedule. Our leadership position will not change next week, next month or even next year and when the market place improves we will benefit first and we will benefit the most. I am also very proud of how Katie Couric and our entire news team distinguished themselves in 2008. Evening news viewership is up and 60 Minutes has continued its tradition of setting the standard for in-depth coverage including the first interview, hosted by Katie, with US Airways Pilot Captain Sully Sullenberger. As the media landscape becomes increasingly crowded shows like 60 Minutes only become more valuable. In sports we finished the NFL season with more viewers than anyone else. We are also looking forward to the NCAA tournament next month including CBS’ interactive March Madness on Demand which is on track to break last year’s revenue record. We are seeing ratings success with The CW as well. The network has truly found its niche with women 18-34 and was the only one to score year-to-year gains in this demo. Gossip Girl, One Tree Hill and the new 90210 were all hits this year with double and even triple digit ratings gains over the prior season. The CW is realizing the largest viewership gains of any network from DVR usage, more proof of what I have said all along; DVR helps rather than hurts the popularity and reach of our programs. Across the board these ratings successes are very encouraging. Clearly we would rather be able to monetize a new hit show like The Mentalist or an established show like CSI in a better market place but it is important to remember that creating franchise content now leads to revenue growth down the road in areas like syndication, mobile, iTunes and DVD sales. These ancillary revenue streams are an increasingly important part of our future and many of them are becoming a bigger piece of the pie now as well. As I said, non-advertising revenue accounted for 1/3 of our total in 2008. These businesses turned in double digit revenue gains in 2008 and continue to perform very well in the current market place. These non-advertising assets include Showtime, syndication, DVD’s, publishing and retransmission consent fees. At Showtime we have exceeded our expectations both financially and creatively. Showtime added one million subscribers last year bringing the total to 16.5 million driven by our critically acclaimed original programming. Our newest addition, The United States of Tara has now joined Weeds, Dexter, Californication and The Tudors as an established hit, each of which continue to succeed across multiple platforms. For example, through CBS’ interactive deal with iTunes, The Tudors recently spent 9 straight days as iTunes number one downloaded series. The Tudors’ second season debuted in the top ten among DVD sales, a feat rarely achieved by television DVD’s. While others have expressed concern about the DVD business, television DVD’s continue to be a very solid business for us, up mid-teens for the year. Our other non-advertising supported businesses turned in strong results as well. Showtime’s success helped affiliate revenues grow 6% in 2008 and led by the CSI franchise, domestic and international syndication had a terrific year up 41%. We expect a great 2009 as well. Criminal Minds, Everybody Hates Chris, Ghost Whisperer, Medium and Numbers are all being sold into syndication this year. On the retrans front we have signed some significant carriage agreements so far this year, one with Verizon and a major new deal with Time Warner Cable. Today, as you may have seen, we signed a deal with Echostar for retransmission through the Dish Network as well. This year, within the last six weeks we have announced major deals with the number one telco, the second largest cable and the second largest satellite distributor, all of which recognize the value of our content. We said we would get paid for our network and we are. Simon & Schuster which also does not derive revenue from advertising was able to buck industry trends and finish the year with higher fourth quarter revenues. They have digitized more than 17,000 titles and are increasingly entering the e-book marketplace where sales increased four-fold during the year. Building ancillary revenue is a key strategy for all of our traditional media businesses and our new ones as well. Which brings me to another growing revenue stream for CBS, our interactive segment. We are pleased with the successful integration of CNET and CBS Interactive. Quincy, Neal and their team are driving audiences and revenue, increasing profits and creating new growth opportunities. They have redesigned CNET.com and last month TV.com added thousands of videos to what was already a thriving online community. Today TV.com has more than five times the number of video streams it had a year ago and 20 times the total minutes streamed online. TV.com is clearly going to be a very, very big player in what is clearly a fast growing category. In addition to CNET and TV.com, most of our sites had all time traffic highs in the fourth quarter and we are seeing success of our integrated sales approach which allows marketers to buy across multiple CBS Interactive properties and throughout our company. CBS Interactive was able to post top line growth at a time when many of our online competitors were flat to down. Going forward even in a slower revenue and growth environment we are focusing on taking share and dramatically improving our margins. We laid the groundwork in 2008 by realizing procurement and public company cost savings there as well as streamlining senior management and integrating substantial cost reductions. As I said earlier we have only begun to explore all we can accomplish with this business. The early results are already encouraging with Interactive, as with all of our businesses, our strategy continues to be producing the absolute best content and delivering it to our audience how, where and when they want it. At the same time, there is no doubt that our local assets in radio, outdoor and television are three areas that are being hurt right now. In radio we are advancing our strategy on focusing on the largest markets. We recently made deals with Clear Channel and the Wilks Group to sell or swap five mid-sized market stations. Most important to our long-term growth we significantly rationalized the cost base of this business, reducing headcount and operating costs throughout 2008 and into 2009 as well. As we right-size this business, large market radio remains a key part of the CBS portfolio and a prime opportunity online as well. We also believe in the long-term viability of our outdoor business as an advertising medium but right now outdoor is feeling the pains of the operating environment. Late last year advertising fell off sharply but billboard lease and transit costs did not which is why our results are disappointing. We have rationalized our expense base in outdoor in all places we control at this time with reductions in headcount and operating costs and those efforts will continue. So will our focus on the growth areas of this business, digital and international. Once again we will manage this business to be well positioned when things turn. Across the company our strategy is clear. We will continue to build out our content on our established businesses and increasingly on the internet as well. We will continue to maintain a strong balance sheet. Our businesses continue to generate healthy levels of free cash flow and we are now retaining more cash in order to be equipped to handle any economic climate going forward. We will continue to manage our businesses through the current climate including a very disciplined approach to Capex and other expenses. Looking forward, as others have pointed out, it is a very difficult time to forecast the near impact of the current U.S. and global economic picture. Given the very positive ratings trends we see at the network and our strong syndication sales with five series hitting the books in the back half of 2009 we believe that the second half of 2009 will be stronger than the first even if the economy does not improve. Once again, while we can’t control the macro environment we can control how we run our businesses and the quality of our content and I am pleased with our continued progress on both fronts. Now I will turn the call over to Fred Reynolds, our CFO, for some additional insight on our financials.
