Leaving behind all other actors in the film industry, megastar Amitabh Bachchan has been ranked number one on Twitter, in terms of both popularity and activity.
In an analytics report of the most popular Bollywood stars on the social networking site, Big B with 12 million followers on Twitter topped the popularity list.
Digital services provider 'TO THE NEW' rated various Bollywood celebrities on the basis of their popularity and their engagement with fans on Twitter.
The rank is based on an algorithm which combines the scores received for each measure i.e. total number of followers, absolute increase in followers and tweets per day.
72-year-old Bachchan is followed by superstar Shah Rukh Khan (10.4 million followers) at number two and Abhishek Bachchan (5.4 million) at the third position.
Hrithik Roshan (7.7 million), Aamir Khan (10.1 million) and Salman Khan (9.5 million) have also made it to the list of top 10 most popular Bollywood actors.
Actresses in the list include Priyanka Chopra (8 million), Deepika Padukone, Sonam Kapoor and Sonakshi Sinha.
With an average of 20 tweets, re-tweets and replies per day, Bachchan also came out as the most active one among all.
His son Abhishek came second with an average of ten tweets. Anupam Kher, SRK and Sonakshi are also among the most active ones.
When it came to an increase in the number of followers in 2014, maverick actor Aamir Khan left behind all by registering an increase of more than 45 lakh followers.
Amitabh and SRK also saw a similar increase followed by Salman and Deepika.
The report also analysed 100 tweets for the top 10 celebrities during November and found that most of the conversations were on work promotion, interaction with fans and friends and brand promotion.
For Big B, 88 per cent of his tweets are interactions with fans. He also retweets pictures of his iconic characters and memorable roles that his fans share with him.
He uses a unique style of tweeting, which includes pre-fixing a number code to the tweet - for example 'T-1375'.
Around 61 per cent of 'King' Khan's tweets are interaction with his fans and friends while 16 per cent of the tweets are about upcoming projects or recently released films.
Aamir, who was not very active on Twitter last year, was seen on twitter mostly while promoting his show 'Satyamev Jayate' or his films.
Interestingly, 54 per cent of his tweets were brand endorsements, the report said.
