The Hindi film Industry-wallahs will strongly dislike this post perhaps, but I am quite sure without their passive /active participation so many hundreds of Classic and new Hindi films besides regional ones would not be floating on the Internet so freely!
There is no shying away from the fact that now thousands of Hindi movies are available to viewers online.
Many DVD Companies have opened their YouTube accounts and they are offering their copyrighted Hindi films to watch freely online…
Some of the popular ones are :
Mukta arts http://www.youtube.com/user/MuktaArtsMovies#g/search
There are of a no of others which store vast volumes of Classic 60s and 70s bollywood films like stagevu.com, veoh.com, join4movies.com etc.
A lot of online watch link sites are available like www.onlinewatchmovies.net, www.bharatmovies.com, www.filmlinks4u.net/ etc where links to other sites having movies like youtube, megavideo, mediafire etc are stored
Then there are forums where movies in downloadable parts are hosted like :
So many to choose and so little time to write. Make Google your guide as usual!!
