Eighty-five positions were eliminated this week at the Tampa Tribune, TBO.com and WFLA News Channel 8. Parent company Media General blamed falling advertising for the cuts, the second round of layoffs since March. The Tribune newsroom let go 17 employees and WFLA released six people and declined to fill two open positions, the company said. One of the highest profile layoffs was that of Bill Ratliff, a WFLA morning news anchor who announced in April that he had accepted a severance package. Like most newspapers, the Tribune has been losing circulation as readers gravitate to the Internet.
