Twitter may become less interactive and more an advertising broadcast medium like TV or radio Posted: 29 May 2013 09:10 AM PDT Popular social media site Twitter may eventually resemble a broadcast medium like television or radio, with users reading messages written by celebrities and corporations rather than writing their own "tweet" messages of up to 140 characters, suggests a new study.
