Samsung TV's apps marketplace features 200 applications.

Samsung has hit an important milestone with the apps marketplace on its HDTVs.

According to the company, 1 million applications have been downloaded from its Samsung Apps since it launched in March. Samsung said that Hulu Plus, ESPN Next Level, CinemaNow, and Texas Holdem are among the "the most frequently downloaded applications" in its store. In addition, the company said that Samsung Apps now features 200 applications, including MLB.TV, Vudu, Netflix, and many others.

Currently, Samsung offers its marketplace on over half of its 2010 line of HDTVs. The company said that it expects TV vendors to sell a total of 6.5 million HDTV units featuring applications by the end of the year. By 2012, it believes that market will expand to 20 million unit sales.

Most major television makers also offer apps on their sets. And one of those companies--Vizio--is battling it out with Samsung for dominance in the HDTV market.

According to research firm iSuppli, Vizio led the LCD market in overall shipments during the third quarter, nabbing 19.9 percent market share. Samsung came in second with 17.7 percent market share. But when it came to all television shipments to the U.S., Samsung was helped by an increase in plasma sales. The company led the way in overall TV shipments with 19.3 percent market share, besting Vizio's 17 percent overall market share.
