Mini, the orphaned cat, shares the roof along with the caretaker-cum-gatekeeper of this south Kolkata cinema that downed shutters last year.

Welcome to the world of 26 leftover single-screen theatres in Kolkata, which are closing down at a pace that doesn't care for speed-breakers.

It's only after a good 15 minutes that he identifies it as a reel from the Amitabh-Rekha starrer 'Silsila'. Today, all that is just memory," he says, rubbing his eyes.

In the week before its final closure, a cruel joke would do the rounds.

The last film to be screened there was 'Belaseshe', the Soumitra Chatterjee-Swatilekha Sengupta starrer. "How ironical that this film should have marked the 'bela sesh' (end of days) for the theatre too. It brought such a sense of closure," he smiles wryly, eyes glistening as he walks past the debris, leading the way into what used to once be a favourite entertainment destination for many south Kolkatans.

The country's Supreme Court last month refused to block porn in response to a petition that linked it to sex crime, which was taken to mean that the country would not impose such a ban.

But the home ministry submitted further information after that ruling and the ban followed a letter sent to the telecom secretary, according to Reuters.

The order to block the sites was received late on Friday and asked the bans to be put in place by today, Live Mint reported.

Banned sites seem to show up in different ways depending on the internet service provider, either showing a message telling users that a site is “blocked as per the directions received from Department of Telecommunications, Government of India”, or just not showing at all.

The fire simmers long enough to let the 75-year-old boil some rice as she stares at the empty auditorium. Mother and son wept like inconsolable babies after the final curtains came down after the last show at the theatre. Someone told them that a scrap dealer might sell it off to some small-time caterer to make use of as a curtain. "Maybe someone somewhere will use it for projections in a village..." Bishnu's voice trails off.

Her husband used to work here as a mason before the hall opened on February 4, 1977. There wasn't a single day when I didn't watch a film. Upstairs in the projection room, nothing much remains, except for some torn bunches of unsold tickets and film reels.

The ban includes 857 sites, according to local reports that cited telecoms companies.

The full list has been posted online by the Centre for Internet & Society, in a document that many have pointed out is a hugely comprehensive list of many of the most popular porn sites.

Statements from the Indian government seemed to indicate that it was behind the ban.
