If you were a fan of IAC/InterActiveCorp, you have a lot more to love. Yesterday, the company officially split into 5 different publicly traded companies, a move that is designed to provide more focus and value for investors than the conglomeration offered as a whole. Below is a breakdown of the new companies, their tickers, and their performance for their first day of public trading:

• HSN Inc. (HSNI) comprises the home shopping network properties. Shares of HSNI began trading yesterday at $11 per share, and closed today at $15.92 - a gain of 44.7% for the equity.

• Interval Leisure Group Inc. (IILG) is made up of IAC's time-share businesses. The stock opened yesterday at $12.88 per share, and finished today's trading at $15.06 - a gain of 16.9%.

• Ticketmaster (TKTM) is the sometimes despised (by Pearl Jam at least) and sometimes celebrated (when they don't sell out of tickets for your favorite band before you get there) national purveyor of passes for concerts and events. TKTM shares opened on Thursday at $20.20 per share, and closed today at $24.56 to bank a 2-day gain of 21.6%.

• Tree.com (TREE) represents the company's "Lending Tree" real estate businesses. Because of its close ties to the housing market and the subprime and credit crises, TREE has been the most volatile of the IAC "quints." The stock opened yesterday at $7 per share, tagging a low of $6.98 and a high of $9.00 on the session. Today, TREE closed at $7.99 for a 2-day gain of 14.1%.

• IAC/InterActiveCorp (IACID) is the "catch-all" company for what is left of the conglomerate, including Ask.com, CollegeHumor, and Match.com. IACID will trade just as the original company, with its ticker reverting to the original "IACI" after 20 days due to Nasdaq rules. Since Wednesday, and the breakup, IACID has gained more than 12.3%.
