A review by the London Stock Exchange today could see ITV drop out from the 100 biggest listed companies following a miserable year for the company, which has seen its share price fall by 60%.
The media company will join former FTSE 100 companies Yell and the Daily Mail Group (DMG) in the FTSE 250.
There are now only five media companies in the FTSE 100 compared with 10 at the start of the millennium.
Andy Viner, head of media at BDO Stoy Hayward, said: "Media companies are really struggling in this difficult trading environment, particularly as spend on classified advertising is falling dramatically.
"Media companies also rely to an extent on consumer spending, which, as individuals reign in their finances, is drying up."
Number of FTSE 100 listed media firms facing 10-year low
The number of media companies in the FTSE 100 could fall to its lowest levels for more than a decade.
